Squamish TT - DNF and un-official 53:05

Went out hard, was doing well and ... flatted. Then re-did the course after the last rider to get an un-official time.

So results are a bit hard to interpret...

Current FTP is 320, With TSB today at about +25, The course was 18k out and back, with about 60m of overall climbing. Complicated slightly by sections of (not all that bad) chip-seal.

Avg power for a pre-ride of the course last week was 318, or just below FTP.

My first attempt today lasted 19 minutes about 12k into the course, and ended with a flat on the rear. Avg power was 351 watts.

My second attempt about an hour later was 53:05 (after cycling back on borrowed wheel) and avg power was 326, with avg power of 338 for the equivalent part previously done. Down by about 13 watts.


So I'm guessing that avg power would have been well over 330 if I had completed the first attempt.

Or that tapering got me at least 10 watts over my FTP on this course. Possibly as much as 15.


On the Ryder 8K TT last Wednesday, my avg power was 379 compared to 352 two weeks previous to that. So on that course (11 minutes) tapering apparantly got me about 25 watts. (It was so short, only about 30 TSS points or so, I wasn't too worried about it affecting my taper too much.)


I'll also note that FTP last fall went from about 300 down to 290 while building CTL back up in Jan-Mar this year (with corresponding large negative TSB values.)
