Detroit Free Press Marathon

Comments (431)

Marathon #23 is complete. On Sunday, I finished the Detroit Marathon in 4:41:39. The two smiling faces next to me in the picture are Matt Shobe, who I’ve now done three marathons with, and my running coach Gary Ditsch. They ran with me in Detroit and it was super helpful to have them.

The most exciting thing for me about the Detroit Marathon was that my partner Jason Mendelson completed his first marathon! The whole notion of this is pretty awesome as Jason had major hip surgery eighteen months ago. It was brave of him to take on the training for this and powerful that he got it done.

We had a big party – Becky Cooper, Ryan McIntyre, and Jill Spruiel from Foundry Group also ran Detroit, as did Andrew Tschesnok of Organic Motion, my long time friend Warren Katz (this is his second marathon), and a few other friends.

The day was perfect for a marathon – sunny and cool. I had very low expectations for myself – my goal was simply to finish. I haven’t run much at all since my bike accident in Slovenia in early September and my ribs and left elbow still hurt a little. While I’d done a couple of 10 mile runs, I think I’d run a total of five times since I got back. So my goal was to rely on muscle memory and just get through 26.2 miles.

Matt, Gary, and I went out slow – doing a 2:26 pace for the first half. We were probably on a 2:30 pace through 10 but then picked it up a little after we got through the mile long tunnel that connects Canada and the US. One of the interesting features of the marathon is that miles 4 through 7 are in Windsor Canada – you head from Detroit to Canada over the Ambassador Bridge and then come back to Detroit via the tunnel between the two cities. As a bonus, I learned that South Detroit is actually Windsor, although my guess is that the people of Windsor refer to Detroit as North Windsor.

I turned my left ankle heading into the tunnel and was nervous for about a half a mile but it was fine. I was also claustrophobic in the tunnel – I really hate running in enclosed spaces for any length of time. But we started to cruise once we got back on America soil.

I did the second half in 2:15:13 – another solid negative split.We had been using an 8:2 run:walk pattern up to about 20 and then shifted to 9:1 for the balance. There was a point were I thought we had 4:39 in our sites but we just couldn’t quite make up enough time. But given that my goal was to finish, it was very satisfying to turn in another sub 4:45 marathon.

I had a blast in Detroit from Friday until I left on Tuesday. I spent all day Monday with entrepreneurs and the activity in the core of Detroit around the emerging Detroit Startup Community is really exciting. Look for a longer post on Startup Revolution from me in the next few days about my thoughts on what’s going on there.

If you see Jason this week, give him a high five for his amazing achievement.
