After this morning's ride, I am at 330km of the 500. I don't normally spend this much time on the trainer, so this has been a good experience and good challenge overall. Pace partners have been super fun, but the lack of rest days has caught up with me. When the dust settles I'll be putting the C and D partners into my weekly rotation.
I should be able to grind out 60km for the next 2 days and then finish with the shortest Fondo on Friday.
