Just finished up 22 weeks training for a Labor Day Marathon for which I averaged 76 miles per week and did 13 long-runs of 20 - 24 miles. Finished the M in 4:02 and had nothing left in the tank. I had strong muscle cramps afterwards ( what am I thinking, all muscle cramps are strong and suck...) but no pulls or bruises, just normal soreness. I have started running at recovery pace and have signed up for a 50k on October 28th. It's a road run on hilly course and I am wondering about the mileage and a training schedule to allow recovery now and some preparation for the 50k. How many long-runs should I do between now and then? I have never gone past the marathon distance and will be doing this to finish. Other than this forum of course, could anyone suggest some resources and training schedules for doing ultras? I want to be ready for a 50-mile trail run next May. FWIW I ran over 2,600 miles last year and have ran nearly 2,100 miles in 07. Thanks!
