The goal here is to find the speed that allows you to hold a constant HR for each of the 3 reps.
You have a range of 3-5bpm to work within.
Your goal pace is Vdot MP (approx 80%mhr)
If your HR strays outside of this then you'll need to reduce the pace
This session is designed to develop your aerobic capacity. It's a tough set and you will need to be rested and extremely motivated
These intervals are done at 92-100%mhr although with such short intervals it will be difficult to get your HR into the correct zone. Just go by effort 9.5 or 10/10 on RPE scale
If you are using power then aim for 110-115%ftp
BT: "KEY SET"
Endurance run - Steady run designed to build endurance. Your effort will probably be Vdot E/L pace For the warm up rather than doing a formal set of strides just run for 10 mins as 15s fast cadence and 30s EZ jog on a flat part of your route then drop into your long run pace
"All day" pace, or classic long slow distance (LSD) training. Sensation of leg effort/fatigue generally low, but may rise periodically to higher levels (e.g., when climbing). Concentration generally required to maintain effort only at highest end of range and/or during longer training sessions. Breathing is more regular than at level 1, but continuous conversation still possible. You shoul;d finish feeling pleasantly tired, not exhausted If you do this on the indoor trainer then ONLY RIDE FOR 1HR 40 MINS
