  • Figuring out aerobic HR zones: PR in the marathon is a 2:52. MAF is 148 and a 7:00 pace. Training Peak says aerobic zone is up to 156 HR (sub 7 pace). Stay at 148 or push the 156?
  • MAF is based on fat-burning and metabolism, whereas most other HR zone methods are based on cardiovascular metrics: listen to use discuss this un detail on ATC 226.
  • MAF as a range and not one set HR.
  • When MAF feels hard.
  • Coming back to running after two stress fractures on tibia. Training again for marathons. Current MAF pace is in the 8:30’s (faster than before) but having to force that pace; it feels a lot better to run at a lower HR in the 120-130 range with pace in the 9:00’s. What to do: Force MAF or run at what feels more natural?
  • The art of coaching.
  • If an athlete having mental issues with running sometimes it’s best to throw out the HRM.
  • Ironman athlete having trouble with MAF: 148 too hard to run at but 140 is a lot of walking. How to figure out what the right HR to train at is? or maybe…. just go out an run and find the fun again?
  • Probably not always best to use race data to set HR zones especially for triathletes.
  • Getting into the world of competitive cycling: which category to register in, join a cycling team or club and what style of race is good to start out with?

    Yep you start at Cat 5 with Cat 1 being, or was when I raced as a 2, for national team members. You have to place/win to move up and also be a safe rider. Not too hard to get to Cat 4 and 3 is not too bad but to get to a 2 is harder as is the racing.
