Doesn't seem like we have a running-thread which is quite odd. Well, I'd understand since I really don't like running.
But, I still signed up for a marathon 2 weeks ago and ran it today. Having never run more than 12 kilometres at once, this kind of a big challenge. Don't get me wrong, it would obviously be very hard, but it seemed i underestimated it quite a lot. I was under the assumption that I was en very good shape (despite not really running) and just needed to pace myself well. After all, I could run 4:40/km on 12 kilometres and 4:00/km on 5! I know, not very impressive, but better than I've run for many years.
My goal initially was 4 hours, but that was quickly out the window. I could feel it right from the start, my heartrate would be rather high, but I'd still continue to run a pace much higher than 5:40 (that should have been 6:00, really) that I had planned in order to finish in 4 hours. I guess the clapping and the emotion got the better of me. Meanwhile, I was thinking to myself (you think ALOT during a marathon) that I was no Skybot and ran on instinct rather than on watts and km/minute. What a fool I was. Always be a Skybot in that situation and never Contador. It has to be boring the first 10 kilometres, the pace slow, but yeah. You got do get that experience firsthand, it doesn't matter if you read it on the internet or your running mates tell you.
So I completely bonked after 25 km, we are talking about Landis on La Touissuire and Ullrich on Galibier-levels combined. The only difference being Ullrich actually raced the best climber ever while I raced old men and women who beat be comfortably. Went from 6 min/km to 8 min/km and was close to retiring multiple times, but somehow pulled through.. honestly, I don't know why I continued, but it feels great. Apart from the pain when Im going to the toilet or want to make me food. I have the feeling I'll never be the same again.
Anyways, it confirmed that a) you actually need to train for a marathon and b) i like my bike better. Not really surprising conclusions, but what an experience. You can find the run on Strava, Andreas Riis. Running time is 4:40, but I completely in exactly 5:00 due to long breaks in the end.
