Yeah, don’t do TT pace every day (unless you want to accept the pain), eat what you feel like, eat as soon as you get to work and as soon as you get home to aid recovery.
Oh and I recently read that the whole ice baths thing doesn’t work – the inflammation and pain are all part of your body adapting, so reducing the pain will reduce the training gains.
I have a similar commute and it took months to really be able to press on on Monday/Tuesdays without the fear of very slow days later in the week, but much better now (except when it’s really windy).
(edited as I’d waffled quite a lot)
