Oh no! I leave Monday morning for a two week hike across the Grand Canyon! I thought that all the biking would really help train for this trip! Actually, my BF has always been a biker. Whenever we hiked, he always said that his calves hurt too. Guess I'll be hurting pretty bad too. Is it the downhill or the uphill that makes it worse? Obviously, I'll be hiking downhill first. (We're starting on the North Rim, hiking to the river, across and then out Hermit's, rest, then back down Grandview and across to the North Rim.)
