Cerys improved her 10 mile PB from 37.42 to 36.00 last night; an improvement of more than 6% (and 10% on her immediately preceding effort). Also impressive was how she did it: she thought my pacing plan made sense and tried to execute it. Here is her ride last night as a comparison table:
Very very consistent within each lap. Looking at the overall times her first and last laps were similarly speedy and the middle two are a little bit slower. The next thing for her to work on is her breathing because this performance was adversely affected by a stitch; an indicator of shallow breathing.
