So just to put this in perspective, I rode a double century in July (1 1/2 months ago). I’ve kept my fitness up, and live in a two story walk up condo, with a dog that I have to walk multiple times each day. I average 100 miles a week on my bike and 15 flights of stairs daily.
With my bike needing some repairs I needed to do something until I could take it into the LBS.
So I’ve done SI 1A before and figured I should start there instead of doing SB 1A…
That was two days ago and my legs are killing me tonight. 20 minutes…. DOMS the gift that keeps on giving!
