I used 2012 description based on MapMyRide climb descriptions. Now, I use ridewithgps for mapping which doesn't have Cat 5.
There are 7 Strava segments. The KOM and QOM for each segment will be honored with appropriate SWAG during the post-ride lunch, assuming everyone can get their rides uploaded to Strava immediately after finishing.
UPDATE: As of last night We have over 100 riders already registered. 57 of which are doing the 68 miler. Includes 30 riders from The Hills area. Still a bargain at only $35. Snares you 2 meals, snacks/drinks, T-shirt (if registered before 6/20), mobile mechanic (Harlans Bike & Tour of Sioux Falls). Limited to first 200 riders. Here's a short video clip of the 2012 ride, same route this year.
The quality of riders is improving each year. Now, in our 4th year, we expect to attract an even greater number of strong riders. Hoping some of them will be you!
Finally, no fee to enter the park and camping onsite at the Group Lodge is available. Lodge has showers, full kitchen, etc.
