One of my standard long rides nicely matches up with TR’s Disaster workout in terms of duration, TSS, work in kJ/calories, IF, and even roughly similar % time in zones as I mentioned here WorldWide "Disaster" Day - Dec 15, 2018 - #498 by bbarrera
Riding time:
- 4:15:00 Disaster on trainer
- 4:15:47 my 70+ mile ride
Elapsed time I estimate at roughly 5% less for indoor rides of that long duration, based on the breaks I took on 2-3 hour TR workouts. And that is solo outside ride, so less time waiting at stops.
@REEDBOY - I’d do that substitution if you enjoy 3 hour outside endurance rides! In the past I try and do 2 a month, and have noticed a positive impact on fitness as a result.
