Ice Age Trail 50M

I just finished my first ultra a 60K at Land Between the Lakes on March 8th. I had a blast. The most fun that I have ever had running....six inches of snow and 37 miles and a sense of accomplishment.<br><br>
A friend of mine that ran with me wants to run the Ice age trail 50 miler in May. Has anyone run this race? Tell me about it? How is the course? Is it too soon to run another ultra? I am still in recovery mode now<br><br>
Thanks
