Tie Dye 50k
About this race
Annual Tie Dye 50K
Day: May 16, 2026
Race Start Time: 7:30 AM
COURSE DESCRIPTION
“John Bryan is the most scenic state park in western Ohio. The 752-acre park contains a remarkable limestone gorge cut by the Little Miami River which is designated as a state and national scenic river. A portion of the gorge itself is designated as a national natural landmark.”
Tie Dye 50K IS CUPLESS! This means there will not be cups pre-set at any aid stations.
An ORRRC collapsible, reusable cup is available to be added to your registration for $3 and the cup will be provided at packet pickup.
Please carry it with you as well as your water bottle. There will be absolutely no cups at aid stations (you will need to use your cup if you want to drink Coke or Ginger Ale, or grab some pretzels to go).
COURSE OVERVIEW
3 loop course traversing through beautiful John Bryan State Park–and is the same popular course used the last 4 years. Each loop will be approximately 10.3 miles. The course maps are available below.
AID STATIONS
AID STATIONS: Fully manned aid stations at miles 5, 10.3, 15.3, 20.6, 25.6. Water only station at miles 2.2, 7, 9, 12.5, 17.3, 19.3, 23, 27.6, and 29.6.

DROP BAGS
You can have drop bags at miles 10.3 and 20.6 (Start/Finish). For the safety of you and others, you will manage your own drop back and the volunteers will not access them.
PACKET PICK-UP
Packet pick-up will begin at 6:00 a.m. on Saturday, May 16th, at the shelter in the campground. Enter the park and park in the first parking lot on the right after the park office. The shelter is up against the hill on the left outside of the parking lot.
PARKING
John Bryan State Park, Yellow Springs, Ohio. We will fill the main lot (I will have at least two spots coned for the course). We will also have volunteers helping direct runners to other parking areas. Do not park in the campground unless you have a camping permit.
CUT-OFFS
For the safety of the runners and the comfort of the volunteers, cutoffs will be enforced. Total completion time is 9 hours or 4:30 p.m. To complete within 9-hours you must start your third loop by 1:30 p.m. The sweeper will begin sweeping at 2:00 p.m. and you must stay ahead of the sweeper.
EARLY START OPTION
