Longest Hill?

Box Hill Repeats? There aint a lot of point in using English Hills for Alpine training - I speak having done just that for this years Etape. Flat out on the flat is better but i'd suggest 1 hour efforts not 20/30mins.

yeah wot he said, 3laps of richmond park (1hour) at 70-80% max output would be better than 8min climbs followed by a rest downhill repeated.
