As an aside, my legs USUALLY feel dead for the first 20-40 minutes (depending upon terrain), unless I take it reallllly slow (which I probably only do half the time). That's your warm up time. While it was good to stop and have some fuel, I'll betcha you would've started feeling better if you'd kept going as well. One of SadieKate's mantras for warm up time is one minute per year of age. In other words, give yourself ample time to get the blood flowing, and keep moving if you can.Originally Posted by tprevost
