Event Information
Event Description: You may compete in either a 8-hour or 4-hour race on a 1.65 mile loop course at Limestone Park. The course, mostly crushed limestone and partly asphalt, is about half flat and half hilly with one short-but-steep downhill and one short-but-steep uphill plus a couple of other small hills, with a maximum elevation change of 50 feet. NEW THIS YEAR - During the last half hour, you may switch to a 1/4 mile out and back loop (1/8 mile each way) if you don’t have time to do a full course loop.
How it works: At the end of each loop you will check in with the scorekeeper. Then, take a break between loops or go right back out again; the choice is yours. Do as many loops as you can in the allotted time for your race. The scoring will be based on total loops completed. In the event of ties, the person who finished his or her last loop earliest will be the winner. Partial loops will not count. Use your own judgement about when to start a final loop. NEW THIS YEAR - During the last half hour, you may switch to a 1/4 mile out and back loop (1/8 mile each way) if you don’t have time to do a full course loop.
Aid Station: There will be a well-stocked aid station at the start/finish of the loop, It will be mostly limited to items that are individually wrapped. Restrooms will also be available there. There is an area where runners can set up their own base camps. If you have any special needs/wants for refreshments, you should plan on bringing your own.
Awards: Overall awards and age group awards will be based on participation. Finisher awards to all participants (personalized with your name for pre-registered participants.)
Net proceeds of this event will be donated to: Kankakee Veterans Assistance Commission and Limestone Park.
