Just did Tour de Wyoming.
5 days 17500 climbing
Spent the whole week @7k with the climbs going 9k to 10.8k.
Came directly from Texas @ 650ft elevation
Knocked my FTP down 15% to reset zones.
59 yom with a sub 3wkg at home
THE QUESTION IS
Zone 2 power and zone 2 HR ended up normal but Zone 3 and up HR lagged despite increased respiration. Why is this? This also happened to a same age rider from the same place. He is a much stronger athlete.
