Running as cross-training?

[velo]

If the running is your only exercise for a month- you may be pleasantly surprised at how the proportion of running to walking and your speed in general improve! (: Even if you can't run an equivalent time to start- just walk fast when you need a break........In the years I coached track I was always so happy to see those kids that could barely do a lap or two progress to 5k by the end of the season (:

Thanks, tealtreak! How often and for how long jogging each time would be a good goal for those weeks that I can't be in the saddle at all?
