Yes, at the moment I run 10k twice a week and 20k+ once a week, plus swimming 2.5km twice a week (plus training session), in addition to the cycling. But then again, I am training for a stupendously stupid triathalon event (36 hours non-stop). I don't know if it's helping my cycling much, but I was the first man home in a 10k running race on Sunday... and I am probably fitter than I have been for several years.
