Marathonfilter. In about 3 weeks I'll be doing the P.F. Chang's Rock 'n' Roll marathon in Phoenix. This will be my first marathon... and while I'm not really that concerned about my time as long as I make it across the finish line, is there anything else a person can do in the final weeks to prepare?
