The plan I found to begin with is 3 days a week after 30-45 minutes of cardio, and 2 days of weight training, with the weekends off. My plan is to use bicycling as my "cardio".
Since my list includes riding in the Miner's Revenge bike race in MI I figured using cycling as exercise now will help with that. I also plan to "thru-bike" a 65-mile trail nearby next summer.
Starting with riding my bike three days a week, and at least six miles a day (I'll increase that gradually) hopefully I'll be ready to do my thru-bike, and it'll be good exercise! At least until is starts to snow, and then who knows... So I have until October or November, and then from April until July to be ready!
