Better performance, worse time

It’s Wednesday, so last night was time trial night as usual. Here are my down and up splits in the format we’ve seen before:

Down Up Delta Total
Time Power Time Power Time Power Time Power
3.45 176 3.40 249 -0.05 +73 7.25 212
3.56 168 3.46 244 -0.10 +78 7.42 205
3.34 220 3.39 245 0.05 +25 7.13 233
3.35 219

Compared to previously these splits are much better paced, as you would hope given I now knew what I should be doing. I clearly took it too easy on the first two laps, dropping around 30 seconds that I didn’t need to drop.

For this ride I did not fit aerobars or attempt to adjust my position. I rode my bike in its road-bike configuration, which I could feel allowed me to produce more power. My time was 29.30, 19s slower than my PB (set with aerobars); on average the other riders who rode on both occasions were 49s slower, so I think my performance has actually improved.

Cerys’s splits are also different to her last ride:

Down Up Delta Total
Time Power Time Power Time Power Time Power
4.13 259 4.45 235 0.32 -24 8.58 246
4.19 251 5.00 222 0.41 -29 9.19 235
4.20 240 4.51 226 0.31 -14 9.11 233
4.17 254

Her pacing looks to be worse than previously. Her time was 36.41, 41s slower than her PB; on average the other riders who rode on both occasions were 53s slower, so again I think her performance has improved.

Between this ride and the previous one we had Cerys’s bike professionally fit to her in order to optimise her position. This lets her access more power more of the time; I suspect she enjoyed the sensation of power so much that she forgot all about pacing. Hopefully we can put it all together next time out and she’ll be able to clock a sub-36 time.
