Indoor rides when bad weather

[andrew1]

Hi
I imagine that this subject has already been done so please feel free to link any previous answers.
I have a 2 hr/100tss endurance ride to do on Saturday and the weather looks awful.
What are the recommendations to FTFP?
Zwift for 2 hrs at a constant power or for 100 TSS within the recommended heart rate. Happy to do either
Any thoughts?
Thanks in advance

Hi Andrew,

Yeah this come up a lot last year! Here is a link to one of the threads.

Indoor trainer sessions - how long?

Yeah we try to keep indoor training rides shorter especially this early in season and winter. Most likely are looking at having to do multiple training rides over the next 4 - 5 months! It is easy to get burnt out on the trainer so these longer rides indoors become more important come February / March then they are November and December. Typically no more than 90 minutes in November and December. Come February and March 2 - 3 hours. Now endurance rides also aren’t TSS rides so you shouldn’t ju…

But basically with it being early October and most likely early in your training cycle there is no reason to hammer away on indoor trainer rides. Cut it down to 60 - 90 minutes max. You can add some tempo / sweet spot efforts to help bring the TSS up closer to 100 all the while keeping the effort aerobic based.
