An important element of training that often gets neglected by runners is cross-training. A typical training plan will incorporate a couple of rest and/or cross-training days. Remember what I said in the previous posting; be sure to use your rest days for rest. But, what should you be doing on your cross-training days? You know when you go to the all-you-can-eat buffet and there stretched before you is an entire bounty of goodies? You also know how that bounty includes some healthy choices and a whole lot of not-so-healthy-choices? Well, cross-training is just like that.
