Alan, just out of interest, why do you think that running keeps your weight down particularly? An hour on the bike costs me 800-1100 cal depending on what I'm doing. I can't see running being much higher than that!

Just found this on web http://www.drmirkin.com/fitness/run_or_cycle.html not sure how accurate it is but it seems to support the running argument.
As Lee points out running has more injury issues.
The Martin Eadon vid's are very informative, ta.
In previous seasons I've pretty much gone into racing off a road season. Gonna built up my Kross and get out on the dirt, my usual first race = first ride on cx bike = disaster.
Anybody find any relevance in riding mtb races during summer?
Still 3 Mars bars per hour though :-)
