CAN I GET A REFUND IF I CANNOT RUN? There are NO REFUNDS, NO EXCEPTIONS. However, we DO allow TRANSFERS and DEFERRALS. See below for details.

CAN I TRANSFER MY REGISTRATION TO SOMEONE ELSE? YES! Thru October 10, 2021 you can transfer your entry to another runner by logging into your Race Roster account and following the TRANSFER instructions. For example, if you paid $80 to register for a race and you are transferring your entry to someone else, the new registrant will only be charged $10 which is the transfer fee. It is up to you to collect the $80 from the new participant. NOTE: NO TRANSFERS WILL BE PERMITTED AFTER OCTOBER 10, 2021.

CAN I TRANSFER MY REGISTRATION TO ANOTHER RACE? YES! Thru October 10, 2021 you can transfer your entry from one race to another by logging into your Race Roster account and following the TRANSFER instructions. Cost: $10 plus the difference in price for the race you originally registered for and the new race you are transferring to. For example, if you paid $80 to register for a race and the race you are transferring had a registration price of $100 on the day you originally registered for the first race, you will pay the $10 transfer fee plus the difference in cost between the two races (in this case, $20). Total cost of $30. We do not offer refunds if the race you initially registered for is more expensive than the race you are transferring to. in some cases, the race you are transferring to may be more expensive than the race you originally registered for. For example, if you registered for the one race when it was at it's lowest tier and then later decide to transfer to a shorter distance race that is now at a higher tier, you will have to pay the difference between the two races (plus the transfer fee).If a race has reached capacity, no transfers into that race will be permitted. NOTE: NO TRANSFERS WILL BE PERMITTED AFTER OCTOBER 10, 2021.

​CAN I DEFER MY ENTRY UNTIL 2022? Yes, we have a  "NO SWEAT" deferral policy! You can defer your entry one year (to 2022) thru October 10, 2021. No deferrals will be permitted after October 10, 2021 - NO EXCEPTIONS. The deferral cost is $25. When the 2022 registration opens you will be sent an email with a code to use that credits you with your 2021 registration fee less the $25 deferral cost. If, for example, you register in 2021 for $100 and choose to defer your entry to 2022, you will be provided with a code that will give you a credit for $75 ($100 less the $25 deferral fee). No refunds will be offered if the price you registered for in 2021 is higher than the 2022 registration price. You will still have to register for the 2022 race using the code we provide. If you wish to defer, send an email to

IN 2020 THE RACE WAS CANCELLED. IS MY DEFERRED REGISTRATION FROM 2019 OR MY 2020 REGISTRATION CARRIED OVER TO 2021? Yes, although registration is NOT automatic. You should have or soon will receive an email from Race Roster (around June 4 or 5, 2021) showing your entry for 2021. All you need to do is to confirm it. 


WHAT IS YOUR RACE CANCELLATION POLICY? The Race Directors reserve the right to modify or cancel the race or course for safety concerns, trail condition concerns or natural disasters. In such cases, there will be no refunds of race entry fees. Each athlete must accept any such risk of their entry fee paid. There is no complimentary race entry to a future race. Entry fees collected are used to develop and produce the event, starting well in advance of the race date - including course preparation, race supplies, permits and administration. We will make every effort to produce a fair and safe event for all participants. Any decision we make that impacts the race date or potential cancellation is carefully considered and based on the overall event safety, sustainability and manageability. If the race is cancelled, you will still be able to pick up your t-shirt and any other swag items at the race race venue. All details regarding cancellation, if it occurs, will be posted on our Facebook page as well as on the main page of this website and an email blast will be sent to all registered participants. For your information, THIS EVENT HAS NEVER BEEN CANCELLED.  


POST RACE LUNCH  We will have a grill cooking lunch (dinner) from 10:30 until sunset. Choice of beef or veggie burgers will be available. In addition, each runner will be given a selection of chips, drinks and a cookie. The tear-off tag on the bottom of the runner race bib will be the lunch meal ticket.

Race morning check-in is mandatory!  A selection of bananas and coffee will be available as well as water and a sports drink on Saturday morning.

We do NOT offer Race Day Registration. 

The course is a fine, crushed limestone and in very good condition and we hope it will remain that way for Race day. Please remember the weather can change and have a significant impact on your choice of clothing and shoes. Plan and prepare accordingly. This is a TRAIL RACE so you may encounter areas where you may run through some water. This race is run along the Des Plaines River which floods during heavy rains. If the course is flooded we will run the ALTERNATE course.

The DPR Trail Races are not like a big city marathon where you might have a cleanup crew follow behind the runners and pick up debris. Our races are held on Forest Preserve District trails which require a permit for activities. Part of our permit requirement is that no litter will be found on the trails during or after the event. We rely on the runners to be responsible for disposing of their refuse properly. Trash boxes will be placed about 100 yards in either direction from each aid station so please use them. Please do not leave cups, gel wrappers, clothing or other items anywhere on the trail. If you produce trash while away from an aid station, and have already passed the trash box, please carry the trash with you until the next aid station.

Please, no littering anywhere on the any time. Need we say more?
