I’m not a racer, but generally do a few sportives a year. My main focus is on fast midweek club runs in the Summer months (no drop social rides, but very competitive up the hills).
I generally start with TR around November time, train exclusively indoors until around March when I mix in the odd outside ride. Then when it gets to May I just ride how I feel like and do any sportives I have in August/Sep. After that I usually have a month off the bike (or maybe a ride per week) to give myself some proper rest.
This year all that’s gone completely out of the window and I’ve been on TR since January with the exception of a cycling camp in Mallorca that I managed to sneak in just before Covid hit.
