The Little Miami Dirty Dozen

A baker's dozen of the choicest climbs in the Little Miami River Valley

9:00 AM - Saturday, November 7, 2026 - Corwin, OH
An A-group for hill points, and a B-group to enjoy the hills!

The 17th annual Little Miami Dirty Dozen will be held on Saturday, Nov. 7, 2026, starting in Corwin OH.  Plan to be there ready for a start at 9:00 AM in the Little Miami Trail parking lot.  We only race uphill, then regroup at the top of each hill and head for the next one to do it again ... and again ...  Be sure to rally your fellow riders up the hill from above (after you've summited ahead of them) -- with appropriate cheers.

The route has 13 challenging hills.  Along the way, if your legs are not quite up to the challenge, or your schedule requires you to bail out early, just head downhill to the Little Miami Trail and then north back to the start.  Thanks to David Hoptry, the route is on Ride With GPS.  To get a gpx file to transfer into your GPS unit, at the top of the left panel, click on the "More" button, "Export as File", and expand your desired file format to see the download button.

A-Group

The LMDD uses a points system with 5 points awarded for first place on each hill, 4 points for second, 3 points for third, 2 points for fourth, and 1 point for fifth place.  The winner is the rider with the highest accumulated number of points, and wins the honor and respect of your fellow riders.  If your significant other isn't climbing or you're a fan who can help identify point winners at the top of the climbs, we can use your help.  Remember, we only race uphill, regrouping at the top of each hill.

This is a no frills event.  We need one rider to be the A-Group Leader and blow the whistle in a rolling start to begin the racing at the bottom of each climb.  It's best if you know the course and where the hills begin.  If you would like this privilege, let me know when you reply that you're participating.

B-Group
A separate B-Group.  Same time - Same location - Same route, at a less intense pace.  We will definitely re-group at the top of each climb and ride together to the next one.  We can stop in Morrow enroute for a refueling snack, as needed.

Origin

The race is modeled after the Pittsburgh Dirty Dozen, which was created by Danny Chew and now attracts 300+ riders.  The LMDD uses the same type of points system as the PDD, Some pictures from the 2010 LMDD.  See how we're bundled up?  Historically held on Black Friday, the switch was made in 2025 to the first Saturday in November, so it's a little warmer.
