10s sprint with a long recovery period like 90s does not make anyone a good climber.
A 2km climb with a light gradient 7% takes about 6-7 minutes at a joke amateur level. So you need to increase your threshold and VO2max power.
On Monday, for example 3x10 min lower threshold 93% FTP with 5 min slow pace 55% FTP in between. Next week, 3x12min, then 3x14min. If you want to make it more useful, use a low cadence 75-80rpm.
Free riding on Tuesday. On Wednesday, maybe 7x5min pyramid lower Vo2max to tempo. 1min 108%FTP + 4min 87%FTP then 3min easy ride; 2min Vo2max + 3min tempo; 3min Vo2max + 2min tempo; 4min Vo2max + 1min tempo etc I think the pyramid pattern is clear. Again, if you want it to be more useful, do the Vo2max parts at low rpm.
Free ride on Thursday. On Friday, maybe 2x10min lower threshold with a 5min easy ride in between, then 4x3 min lower Vo2max with a 3min easy ride in between.
Saturday is a free ride, but it should be a long. Sunday should be short, but include a few high intensity intervals.
