Back to topic, please. The Iron Horse is a road race, pedalers versus a train. It isn’t offroad muni…it’s all pavement over big Colorado passes. I believe that Aspenmike is the only person that has ridden it start to finish. You should PM him if he doesn’t jump on this thread.
I did a quick search and found this thread on last year’s event. Mike did a super-detailed write-up of his ride experience last year.
Good luck Tom…it sounds like a great event. Maybe you and Mike will double down on the uni finishers this year.
