Topic request (and I feel dumb asking): for the aerobic days, training peaks references “RPE”, which I’m unfamiliar with. I looked up what 5-6 RPE is, and I definitely get over my aerobic threshold HR if I run at 5-6.
Is the idea to do the exercise (ex 30min run after warmup) as close to the zone 2 threshold you can get without surpassing it? I’m a little hazy on what I’m actually aiming for. How closely should I be watching my HR while I’m running? Is it okay if I’m over for a couple minutes total, or does that end up being quite impactful?
