Unlike TMonk, 80 miles is still more than I'm fit for.
Was aiming for more, but dirt is hella slow, and I'm slower than dirt. Rode to Fairfax, did some hard gravel climbs and some fun double track descents, pinch flatted and then went slow cuz another flat would have been an hour of hiking in cleats followed by a hitch hike.
70 miles today and maybe ~350 TSS. When I don't have a power meter I take Strava average power, and guesstimate normalized power from that. Good enough for the spreadsheet.
