I have always wanted to do an IM too. I have done a few sprint Tri. My legs for the running have been my limiting factor. My hamstrings love to tighten right up. If I focus on a lot of yoga and stretching I can kind of work it out. My running is usually limited to about 4 miles. I think, no I know you can do it. Just take it slowly and let me know how it goes. I think I may try to train for one next year too. Let me know if you want a distant buddy. S
