The Register's Annual Great Bicycle Ride Across Iowa starts July 25. Author: Rachel Droze Updated: 7:40 PM CDT July 16, 2021 DES MOINES, Iowa — With RAGBRAI just a week away, first-time rider Matt Heiller and his teammate Matthias Peters, a returning rider, are winding down their training before hitting the pavement. His team has quite a few newbies, and Heiller admitted they didn't get to train as much as they should have. "Our team has probably not put in enough miles, but I think there's a couple of us, get the adrenaline going, I think we might make it," he said. Heiller, who is from Boone, is spending the final weekend pre-RAGBRAI biking with a friend.
