Our HR zones are almost exactly the same lol. I bought all of your books a couple months ago and have been reading them in my free time in chronological order. First I have to say your “Ask A Pro” is funny as hell and I love a dry sense of humor. I’m currently reading your “Pro Cycling on $10 a Day” and it’s interesting to read about the dynamics of a Pro team. I can’t wait to read “Draft Animals” and keep up the great work Phil Gaimon
