I have started an Ultra Training Guide. You can get to it by hitting the link at the top right of this page or clicking here. This guide will serve as a resource to anyone who is or wants to train for an ultra marathon. It is a work in progress so hang it there. I will be adding to it as I have time.
I want to point out one important resource that I used. The blog titled "I Run Far" by Bryon Powell. Bryon is a very experienced ultrarunner who has countless valuable posts. Two of these posts rise above the rest when it comes to Ultra Training: How to select your first ultra and Training for your first ultra. I highly recommend reading these posts as I used them as a guide for my training program for Holiday Lake. You can see how I trained for Holiday Lake at BuckeyOutdoors.com, the online training blog that I use. If you have any questions you can ask me, or check out Bryon's blog and post comments to him. He was very responsive to me and willing to help.
