Just looking for some ideas and maybe a different approach to this years training. I almost at the end of a two week peak period, which looks like this (below), approx 10-13hrs per wk. During Base I concentrated mainly on SST & Tempo/LSD around 15hrs per wk for 12-16 wks, then 8 weeks of build, mostly Threshold, SST & one break through & LSD per week.

I race mtb xcm, I have two weekend races coming up over the next three weeks that I would like to do well in, what would be the best approach to training over the next three weeks to hold onto my fitness? This will be my third year of structured training and I am always looking for new ideas and opinions.
