  1. Why doesn’t Usain Bolt just keep the same pace for a whole marathon, is he stupid?

  2. I agree somewhat.. for run training I’ve usually just ran at a challenging pace. The past few months I’ve decided to do more zone 2 to experiment, weekly mileage went up, but total ability and overall speed have gone down. I’ve regressed with zone 2. I feel more bang for my buck timewise is with a challenging effort.

  3. For MTB I feel it’s not needed. When you climb you’re going to be at peak heart rate.

    Typically the best “bang for your buck” in terms of performance gains comes from building both muscular [lactate] endurance and aerobic capacity, by pushing yourself to exercise above your anaerobic threshold for as long as you can tolerate, then when the pain gets too much, rather than stopping entirely, recover whilst still exercising at a moderate pace (around zone 2 HR).

    The HR zones on their own are a vaguely useful tool, but can end up being kinda meaningless unless you have approximately average human physiology… 

    Theoretically Zone 4 and 5 are at a level where you’re having to operate above the aerobic threshold, but there’s no way you were fully anerobic for two hours (and change) and still able to post afterwards.

    To be running that kind of HR on a sustained basis you clearly have aerobic capacity and muscular endurance which is significantly better than average, a lower than average vascular capacity, or were very dehydrated.

  5. It’s not your real max heart rate if you can hold it for that long. Still a high tempo ride but that’s not your true “zone 5”. What was your rate of perceived effort (RPE) if you’re familiar with the scale?

    I’ve added a lot of additional Zone 2 training in to my routine in addition to VO2 days. The Zone 2 is boring, but over time it raises your baseline noticeably. You recover from the Zone 5 sprints faster and can do more of them back to back. The other reason I like it is because I’m 46. I can’t do endless training in higher Zones. My body and joints will die. Zone 2 allows you to add significantly more training volume per week without over taxing your body.

    Bro you can’t post a photo of Mount Carbon and zone 5, lol. Go to Belcher Hill or Mount Falcon and really suffer.

    If you want to train as efficient as possible, maximizing your time on the bike, and making the most out of rest days, training in zone 2 a lot will give you a lot of bang for your buck. If you want to just go ride hard and have fun, also sounds great.

    Edit: oh I figured you were asking sincerely, now I realize you are just flexing in a weird way. Lmao. Wow great job.

  9. Tldr: If this was with a watch HR monitor, you might confirm your readings with a chest strap.

    I noticed my HR zones were super high on high intensity rides with my Garmin epix pro watch. I suspected the watch was incorrect so I bought an inexpensive coospo chest strap HR monitor which confirmed that the Garmin was recording excessively high numbers.

    It’s mind bottling that some people spend absolutely zero time warming up. If I don’t spend 5-10 minutes in warm-up, I feel gassed within 20-30 minutes of trail riding and can’t ride nearly as long in total.

    If I do warm up, I’m usually not stopping for a break for at least an hour and can do 15 miles without blinking an eye (under normal circumstances).
