I did a thing yesterday
You got to Wowsville! At least in my estimation!
DAMn that's some serious riding, hope it all went smoothly and you're getting some good rest today. I've done many gravel rides, but the longest was just over half of the DAMn, and nothing at all recently. I'm out for a much shorter and easier ride around Mpls today.
It was awesome getting to explore a part of MN that I've not really spent much time in, @wjcstp. The Minnesota River valley is gorgeous and I had the pleasure of being down in there at misty sunrise. And your bicycling community eats sleeps and breathes "Minnesota Nice" really well. Didn't hurt they offer up a cold pint of Spotted Cow at the finish line too.
