Cycling threshold power in relation to heart rate (strong correlation); race wheels available to rent; view yourself as a sculptor, not a painter.
> Open water swims start today at Quinn's Pond. I measured the water at 59 degrees on Saturday afternoon (increased 4 degrees in a week). We'll be toeing the waterline around 6pm, and use today as an 'acclimation' swim. Travis Wood will be leading an entry-level open water swim workout of about 1-2k yards (depending upon ability). Open to everyone.
> Interesting research looking at the correlation of threshold cycling power and heart rate in cool vs hot temperatures. As expected, power dropped significantly in the hot environment, but the heart rate at threshold stayed consistent. Meaning? Your heart rate is fair indicator of effort despite temperature. Prioritizing cooling on hot days is always important, as well as adjusting your power/pace expectations accordingly. This research was run in part by Dan Plews, who is a Ironman Hawaii course record holder, PhD in Exercise Physiology, and triathlon coach. He runs the excellent Endure IQ website.
