Herne Hill Saturday Training

^48x15 (86.4) ;)

Take adman's and y-s's advice about the 82.8" for a novice session. My first few advanced sessions this year were fine on 46x18 (81"), which is probably around 3-5mph quicker than a novice session.

You obviously don't use a speedo.

Novice session average* speed 16-18mph
Intermediate session average* speed 22-24mph
Advance session average* speed 28mph

Based on last year.

*Bunch during general efforts.
