I’ve read all over the internet that “an hour on the trainer is worth 1.5hrs of outdoor riding” but can’t find any science behind this. If I ride for 1hr at 65% indoors today, and then do the exact same ride outdoors tomorrow, the TSS will be exactly the same. I understand that the road will never …

[image] Andrew.Hood: 1hr at 65% I’ve seen the 1:1.5 ratio but also 1:1:15 ratio from popular coaches. Also, the lower the intensity, the closer the ratio gets to 1:1. Plus, there’s a difference between “moving time” and “power time” (not a real term, but let’s go with it). My last 5hr Z2 out…

For me, even for endurance stuff, I find the trainer a better way to hit the higher end, for whatever reason I have trouble getting a steady 70-75% outdoors, I seem to always default between 60-70%. I rode a solo (almost) century yesterday, my IF was 0.67, it gets easier to put power down on some su…

[image] Captain_Doughnutman: Agreed. On my outdoor Z2 rides I really have to keep an eye on things or I start to go too easy. Just the opposite here, I have to concentrate to stop an outside endurance ride from becoming tempo.
