"If I were you, I would probably hold off on the Ice Age 50K until next year. Your focus this summer is successfully completeing your first triathlon! That is a big undertaking in itself. I would stay focused on that goal, get your body completely healed, strong & then you could always do it next year."
During the Chgo Marathon in October, my first Marathon and longest distance, my right shin was really aching. It put me down for only 2 weeks, probably because I went right in to see my physical therapist and orthopedist and listened to what they told me. I changed shoes, got an orthotic (for my verrry high arches), iced regularly, and learned how to stretch and strengthen properly. And now with the cross-training of biking and swimming my body feels much stronger during my runs.
Here's the year with the 50k..........
3/19.....March Madness Half Marathon
4/2......Shamrock Shuffle 8K
5/13.....Ice Age 50K
5/21.....Cleveland 10K (would do the 1/2 Marathon if I don't do the 50K)
6/25.....Naperville Sprint Triathlon
7/22.....Waterfall Glen Extreme 10K
I've been socially running for 10 years, but this is only my third year of doing races. I haven't done ANY speedwork yet. I've been a back-of-the-packer and my goal this year is to be in the middle-of-the-pack. I'm leaning towards forgetting about the 50K for this year...I'll still have plenty of goals to work on. I'm finding the hardest part of all this is reigning yourself in!!
