The good news is that after the gel/cortisone injections my knees feel much better. Even better, Dr Byrne says that with an early September knee surgery I could ski in January. So, I am all in for that as well as scheduling a late July August trip to Zermatt.
The bad news is that on Thursday afternoon my pulse sort of sky-rocketed on my warmup, and needless to say I cancelled the main afternoon event which was a 20k bike ride. Not much exercise since then because of knee injections, but my pulse remains to be somewhat elevated (as you can see below). More tomorrow when I resume training.
