I was thinking about this thread a couple of days ago and thought about replying saying I haven't had a problem for maybe a year now but without a reply for so long decided against doing so. I attribute the lack of a problem with following a training plan that gives very few rest days (and often do a couple of short trips on my commuter bike on those days). I also fortunately avoided any problems when I caught Covid in the autumn which stopped me training consistently for 3 months, I think this is consistent with previous breaks caused by illness which have resulted in no thigh pain, maybe a higher heart rate mitigates the problem?


Here's a link to the Cleveland Clinic article some possible things you can do to help: https://health.clevelandclinic.org/it-band-stretches-and-treatments-to-relieve-knee-and-hip-pain


"“Continuing the activity that led to the problem isn’t going to make it go away,” says Krampf."

For me, the only two options for recovering are serious rest for about 2 weeks (like 2000 steps maximum) - even walking around the house is a problem or otherwise getting on the bike as soon as it starts to hurt and immediately doing several all out anaerobic intervals from cold (no warm up as this aggravates it) until complete exhaustion. I also think my pain is more forwards of the thigh then the IT band.
 
I have had this issue since I was 25 (I am now 44). Two years ago I started taking allopurinol (200 mg/ day) for gout and have not had any debilitating rhabdo since. I'm convinced this is the reason. It took a few months, but eventually all rhabdo stopped. There is some evidence here: https://europepmc.org/article/pmc/4255256

Allopurinol is cheap and relatively harmless. I've shared this before, but felt compelled to do so again. I went on a ride 3 days ago and am about to go out for a worry free run. I hope this works for some of you as well.

Dear all,
Same problems for me. Huge pain in quads when walking downhill or downstairs. Always in the quads but the leg may very. Also the affected areas may vary.
I have been reading through this forum, and also bikeforums.net.

Just a hypothesis:
- during cycling the muscles are mainly loaded in an concentric way, while walking downhill the main loads are eccentric. Anybody tested this hypothesis?

Also possible:
- disbalance between qauds vs hamstrings / glutes;
- problems to stabilize the legs during landing phase of downhill walking;

All the best!

Long time sufferer here too! Was driven to develop a “cure” but nothing is foolproof and occasionally have set-backs like this past couple days. Finally got a ride in this morning with none of the random excruciating pains.

I like all the theories but as most know the professionals don’t have a clue. I had one doctor tell me it was all in my head and prescribed a tall canister of Calm. (magnesium supplement) Thanks for nothing!

I read through previous posts and it took a while, towards the end my attention was fading so I apologize if I missed something.

Here’s the deal, it truly believe it is all spinal related. It’s inflammation, pinched nerves, all related to nerves getting impacted in the L4 and L5 spinal segments. Wear and tear on the spine also creates stenosis which starts to clog up/limit the space/narrowing of channels where the nerve bundles run through. I’m not sure what it is with the biking but being hunched over in just the right way sparks the nerves that travel through the lower spine. I was about to give it up because getting stranded everywhere, and not being able to consistently compete, or even take a ride with friends was embarrassing.

Triggers: walking down hill, walking down stairs, moderate biking, sitting in the car too long, traveling, vacations, holidays, hotel beds, lifting a bunch of crap like helping someone move.

What’s with everyone’s rest days? And then I realized my travel days are just like rest days, after long trips it comes on like gangbusters! I’ve had the pains start even while driving.

When I was young, fat, and happily drinking beer and margaritas all weekend never had a problem. It was only until deciding to get fit, shed 40 pounds, and enjoy challenging outdoor mountain biking did this all start. I thought the body was meant to perform, and I became the strongest ever in my life from cycling , hiking, and running. (mid 40’s) Eating the healthiest, etc! Then things took a dark detour.

Family wanted me to go on a weekend cruise to Mexico, I thought why not even though it will mess with my exercise regiment, I can always hike the ships stairs like an insane person, plus eat and drink a ton. Waiting to board I had 40+ pounds of luggage in each hand plus Grandma’s luggage draped around my neck, a real workhorse but not knowing the weight of carrying everyone’s shite was slowly compressing my spine.

Ship sails off and hit the stairs to burn some calories before the buffet. Go one flight down and the quads immediately seize, like a cramp but worse can’t even walk. WTF is this some medical emergency? If you stop it relents but if you push through I can’t even think of what would happen. Does it go away, hell no, I think it’s either check into the infirmary or just jump overboard because something serious is going on and you’re going to die shortly anyway.

Alright enough with the stories, have too many of them.

My cure:

If you are out biking and feel it coming on, get off the bike, lay on the ground stomach down and push up with your hands creating the upward dog. When I do this I can feel the pain start to fade away and it departs just as quickly as it got there, why? Perhaps the spine channels open up just enough. Usually hold it for 15 seconds and start biking again. Pain comes back, do it again. I’ve been out in the middle of nowhere and it can take 3-6 cycles of doing this and it’s gone for good for the day. The trick is not to let the pain continue too long because then you’re screwed for 24 hours.

Anti-inflammatories help, but I’m not into popping those like candy. Sometimes they are just enough to quiet down your wiring in the spine.

I just learned that THC/CBD salves really work well after the fact especially on sore blasted quads. CBD alone does nothing. And it has to be potent. If pain is deep in the glutes it can’t really reach, but for pain near the surface it surprised the hell out of me that it can knock it out within minutes.

What you eat or don’t doesn’t matter at all, same with alcohol but to a point. If you go on a weekend bender you inflame your whole body, and if it’s combined with a vacation good luck! It’s easy to fall down the rabbit hole of diet and rare syndromes but none of us ever had a problem before, this is different. We aren’t having some energy conversion problem, crap, I can bike, hike, and lift weights beast mode style while in a 40 hour fast, and feel great.

Sometimes the inflammation is just enough to ruin everything.

Walking down hill just compresses your spine, and it starts! Before I knew how to reverse it I’d go out on a 10 minute walk with the dog and get stuck on a hillside for an hour and unable to walk down. I hike now with trekking poles and that helps.

Stretching helps, especially those that improve spinal flexibility.

Spinal doctors can help, look for those that have decompression machines, and hot/cold treatments, ultra sound/light therapy, etc. It isn’t cheap but may just do the trick, same with hanging from a pull up bar and letting your legs dangle.

Sorry for the book report, hope it is useful!

Hello everyone. I’ve written here before about my episodes. They have annoyed me so much that I decided to try the most desperate advice from this forum. I managed to overcome two episodes. Both occurred, as always, after a break of two to three days after cycling.

1. The episode began to hit me on the 10th minute of my cycling workout, as soon as I started to increase the power a bit. I was so unwilling to accept another forced break from cycling that I decided to push through the unpleasant sensations right at the beginning of the episode. I completed an hour-long workout at the edge of zones 3-4, to the point where the pain became negligible behind this load. However, this pain turned into a familiar muscle soreness (like the second day after my first-ever barbell squats). It was strong but understandable pain.

2. After another break on a gloomy day, I went to the gym. The episode caught me at the beginning of a squat set with back squats. I got scared again and started squatting faster, trying to somehow shake off the sensation. I quickly added more weight and continued squatting until I transformed the sharp muscle cramps back into a familiar feeling of muscle soreness.

I read the new messages in the topic, and for now, I think the idea about the imbalance between concentric and eccentric loading is the closest to the truth. Sugar probably also plays a role.

That's awesome you were just able to "power" through on both episodes. When this syndrome really ramps up powering through will leave most people on the ground (or worse disabled and temporarily in the hospital) and that is why we are here. In my opinion you experienced a very mild case, which is great! Those can almost disappear as fast as they arrive.

Was curious about the most desperate advice you tried? Only asking because tough to go back and read through everything again, thanks!

Sorry, I probably didn't express myself clearly. To overcome this attack by increasing the load - I think it is quite dangerous and desperate advice. But this is exactly what helped me twice. But I think it can have a bad effect on something else, because many people mentioned that blood parameters change, as in rhabdomyolysis. This raises concerns when trying to overcome the attack with load.

Thanks - The upward dog thing helped me complete a session today that otherwise would not be possible. Allthough I probably looked super weird as I was doing yoga on the side of a main road in Mallorca in full cycling gear. It was worth it :) Big thanks

Hi there everybody, another fellow sufferer from southern Europe here. ✔
Keen cyclist, 49YO, 180cm 70kg, ≈650h on the bike / year, and one year dealing with this sh*t. 🙈🙈
Unbelievable this thing goes on since ages without having discovered any solid diagnosis yet.
Just wanted to express my solidarity to everyone affected and share my 2 cents: 🤘🏻 🤘🏻

After having spent a couple of weeks reading all posts in this and the other 2 forums, and having cross-checked with my own experience, I developed the idea that this could likely be a multifactorial issue.

Most recurring potential contributing factors:
- Heavy load of exercise (majority are 10K+ Km or 400+h per year athletes)
- Genetic Predisposition? (To be found)
- Aging (majority seems to be over 35YO)
- Sedentary job (majority seems to report this)
- Alcohol, 1 to a few days before the episode (reported repeatedly and also happened to me). Dehydration?
- Food excesses 1 to a few days before the episode (same as above)
- Flu or viral inflammation just passed (reported repetitively and I had Covid 1 week before last episode). Dehydration?
- Lack of Stretching
- Lack of Warm-up before exercise
- Lack of Eccentric capability / Cycling induced quadriceps imbalance (even if it seems Triathletes can also be affected which would make me doubt this eventuality)

Less likely potential contributing factors:
- Cooler air temperature (seems to happen more frequently at the end of summer?)
- Beginning of Strength Training / Unexpressed DOMS? (one of my episodes happened mid-set of a Squat session just restored at the end of the racing season / Off-season, even if I had 1h recovery ride 3 hours prior)
- Creatine integration / Creatine loading (again I had just restored creatine integration after having dropped it at the beginning of the race season as I don't like those extra couple of Kg). Dehydration?
- Bike-fit / Saddle position / inclination
- Other concurrent conditions such as a herniated disc, Sciatalgy, DVT... (who knows?)

It would be interesting to put some stat together for all of us that have 1 or 2 or more contributing factors in order to understand what the most common are.

Solutions? Don't have one obviously.
Stretching daily plus consistent, repeatable warm-up protocol works best for me.

What a weird thing!
👋🏻👋🏻

Joining the list of sufferers...

Currently experiencing it for the first time in my life.
41y old, coming of a two month block of 20-25h/week. Triathlete.

Same symptoms as everyone. Thighs feel like they will explode, like a massive lactic acid build up.
I experience it even walking the dog for an extend period.

Picking up on @Getting Old Sucks list:

Most recurring potential contributing factors:
- Heavy load of exercise (majority are 10K+ Km or 400+h per year athletes) YES
- Genetic Predisposition? (To be found) Maybe, I will get some checks
- Aging (majority seems to be over 35YO) 41Y
- Sedentary job (majority seems to report this) Yes
- Alcohol, 1 to a few days before the episode (reported repeatedly and also happened to me). Dehydration? No alcohol ever
- Food excesses 1 to a few days before the episode (same as above) Not in excess, normal eating, but good amount of carbs and some treats
- Flu or viral inflammation just passed (reported repetitively and I had Covid 1 week before last episode). Dehydration? Flu, cold (still fighting minor symptoms)
- Lack of Stretching I stretch and foam roll regularly
- Lack of Warm-up before exercise Well, I am not warming up before I walk the dog :)
- Lack of Eccentric capability / Cycling induced quadriceps imbalance (even if it seems Triathletes can also be affected which would make me doubt this eventuality) I would exclude this for me

Less likely potential contributing factors:
- Cooler air temperature (seems to happen more frequently at the end of summer?) Don't know
- Beginning of Strength Training / Unexpressed DOMS? (one of my episodes happened mid-set of a Squat session just restored at the end of the racing season / Off-season, even if I had 1h recovery ride 3 hours prior) I do S&C weekly twice, DOMS feels different. I could trigger the pain today in the gym, so session was over after 15 mins...:(
- Creatine integration / Creatine loading (again I had just restored creatine integration after having dropped it at the beginning of the race season as I don't like those extra couple of Kg). Dehydration? Interesting as I do supplement with creatine since 4 months. I stopped using it today, let's see.
- Bike-fit / Saddle position / inclination Professional bike fit done and its not only related to the bike for me.
- Other concurrent conditions such as a herniated disc, Sciatalgy, DVT... (who knows?) No, nothing that I am aware of


I did experience quite a weight gain over the four rest days of around 3kg. Obviously mainly water, but would go into the theory of water storage and the issue maybe related thereto.

Shortly after writing the above, I thought I may try my luck and hop on the trainer. Pain started to creep up after 4 mins, as soon as I felt the slightest pain, I stopped and stretched the legs. I repeated this game for the next 10 mins and started to wait a bit longer until I stretch and see how bad the pain gets. It got stronger but never to the extend as in previous days where I literally cried on the trainer. Eventually the pain went aways after 15mins and I rode the trainer on easy wattage for 30 mins. The legs did not feel fresh, don't get me wrong, they were still stiff and sore, but I could ride without the pain. I immediately stretched after the ride and feel ok now. I will try again tomorrow and will increase intensity. Lets see, hopefully I am through this for this time...
 
Thanks for sharing Dmart. Can I ask you where you're from? Just to know if it's northern or southern hemisphere and have a clue about the temperature.
I also suspect something related to hydration / blood circulation could be a contributing factor

Ok then, I guess I committed to put the data in an Excel as soon as we reach 20 feedbacks (lesser data is going to be not so significant I believe)

Then, to give everybody some context, thinking over it more carefully, I had 4 episodes so far:
1st end of September 2022
2nd beginning of October 2023
3rd and 4th end of October and beginning of November 2024 (the last one while squatting the day after I had an intensity session on the bike and went for a super-easy recovery ride 3 hours prior the episode).
Every time I was in a recovery week (or a week completely off) coming from a peak fitness form and seasonal best efforts.

More context: in season before race time, I'm someone who likes high volume of endurance pace rides: in April / May I put down a 3 weeks block with 18, 25, 30 hours respectively with zero problems whatsoever during and after the block (had a standard recovery week with 8ish easy hours after that). I wasn't supplementing creatine and Strength training was abandoned 2 months prior...

I find it curious that it always happen to me in the same time of the year.
...But I know, I know: "correlation is not causation"! 😅

🤷‍♂️🤷‍♂️

I'm sure you know that this PITA can lead to Rhabdomyolysis for some people so if you see cola-like pee or if you have any doubt, go have yourself checked (CK, CPK, etc).
This is basically the reason why, if I have an episode I don't dare exercising through but I wait to be back to normal instead.
Cheers!

Quick update. I went for an easy run this morning. 30mins fine, pain started to ramp up afterwards. Stretched and it was fine for a couple of minutes. Repeatedly stretched and ran until I got home. Maybe I was too optimistic after yesterdays ride that its gone...

Just to throw it out there
I’ve been dealing with this for over 2 decades (seems to progressively happen more often the older I get -M45)
I work 60 hours a week on my feet, averaging 35000 steps a day, so far from a sedentary job.
First time this ever happened was when I was 18 years old.
I was a bike messenger at the time and had to get a wisdom tooth taken out in the evening of a Friday so couldn’t drink water during the day (because of the anesthesia) while biking for 8 hours. I had the procedure (dehydrated) took the weekend sedentary and Monday morning 3 minutes into riding to work had the worst episode of my life and had to crawl home.
Dehydration- yes
Alcohol- no
Aging- no
DVT- yes (age 30)
Heavy load of exercise- yes
Lack of stretching and warm up- yes

Been deep diving Into this for ages….

Thanks - The upward dog thing helped me complete a session today that otherwise would not be possible. Allthough I probably looked super weird as I was doing yoga on the side of a main road in Mallorca in full cycling gear. It was worth it :) Big thanks
No problem, sometimes the upward dog is all the difference between continuing on vs having to call someone for an extraction. I usually do a slow count to 20 and towards the end can feel the pains start to disappear as quickly as they came on. But yeah, I'm always conscious of how it looks! I hope more people will try it out and report.

Hey Dmart, how are you doing?
Any luck after having quit creatine supplements for a couple of weeks?
Hope everything is ok at your end...

I stopped it now for two weeks.
To be fair, the problems went away after three days and haven’t come back. I am a bit concerned however, as I am currently on vacation and while I go for a run and the occasional gym every now and then it will be “interesting” to see how things are going once back home and training again.

Problem went away after three days without creatine?

Me, I took 2 entire weeks off since we last spoke, but differently than what you've done, I continued to supplement creatine. The only activity during those 2 weeks has been some 40 minutes walk after dinner in order to burn some extra calorie and avoid putting weight on (which is something I tend to do very much as my appetite always exceeds my consumption if I don't exercise hard) and no signs of any issue.
Last night I've tried 10 reps bodyweight squat and after the first set... Bam, here we go again with the crazy kegs.
This morning I eventually quit creatine. We'll see...

I wouldn’t say it was because of creatine as storages would have been not depleted at all after this short time. I just slowly increased training and stretched when the pain started to creep up. After three days no issues anymore at all.

I just came back from vacation and hopped on the trainer. 90 min Z2, no issues. Only thing I changed is that I went lower on carbs and didn't take creatine. I would like to think however that creatine has nothing to do with it, rather the carbs.

Very good to hear this!
I've done 3x 2h Z2 rides Sat-Sun-Mon and no problems. This week I'm going to try strength training (i.e. Squats) again and see what happens.
I strongly suspect creatine can play a key role in this issue, at least in my case as for 3 years in a row now, the quad seizing issue appeared out of the blue during creatine loading phase.
No hard evidence obviously, just a few clues that I'll keep investigating.
Cheers.
