I will be driving my daughter to college on August 21-23 (Friday Saturday Sunday). This occurs at the end of week 4 of SSB Polarized (with the 20 min test on Saturday). There is a chance I could get back on Sunday in time for a ride but I will have been driving for 8-10 hours.
What do you recommend I do? I could do the 20 min test on Thursday but not sure what workouts to do leading up to that. Or should I do some other workouts that week and estimate my FTP from my rides?
