Packet Pick-Up/Check-In

Check-in/packet pick-up will be at Greenland Open Space, Friday, May 31, 1-6 PM (exit 167 on I-25). Socks, bike numbers, and rules will be available at this time. Race starts promptly at 6:30 PM, Friday and finishes Saturday evening, 6:30 pm. Race and enjoy the post event party!

Chip Timing

The 24 Hrs of ERock will be chip timed. All riders will be provided a disposable bike number chip that will be affixed to the front handle bar. Please plan on arriving with enough time to test your chip by walking across the timing mat in the timing tent.

Chip Timing Part 2

As riders enter the tent, they will be able to view on computer monitors (at the end of the tent), to see if their chip was recorded by the mat. This will eliminate the need to verbally acknowledge each lap by rider & staff. It will be the responsibility of the rider to view the monitors to make sure their bib and time are recorded. Computer staff/timers will be monitoring the computers to view the same.

Chip Timing Part 3

ALSO, we will only provide the chips and bike numbers to ONE RESPONSIBLE member of each team for disbursement (does not have to be the captain).


Camping and Car Camping is available adjacent to the transition area. PLEASE NOTE: Should the county invoke fire restrictions, a no burn policy will go into effect.


Carpooling is encouraged - parking by your campsite will be limited-if you are car camping (pick-up shell, small RV, etc) as part of your team camping, we will allow a vehicle in your area. This is open space and camping is only allowed by the Douglas County Open Space & Trails Dept. for this event, so there are no “specific” camping sites that you would normally find at a state park.

Awards/ Prizes

Awards will be presented to the top 3 teams/solo’s in each category. Random Prize drawings will also be held at the conclusion of the event.


Everyone receives a pair of socks with Registration.


This years jerseys will be sold directly through Shaver Sport. Please go to their web site at to order your 2013 jersey.

The 24 HOURS of EROCK, wants you, the racer, to be unencumbered by an over abundance of rules and have adopted these “simple rules” used by our friends at the 18 Hrs of Fruita.

8. No course support will be provided by the event.
9. Water and food may be supplied to any racer, at the transition area, as long as the racer and support is off the course and does not interfere with the race. Interference with other racers will result in disqualification.

Additional rules or changes may be added as questions arise, so please continue to check this site for updates.

For safety reasons, the event reserves the right to cancel or change a portion of the course, pause or cancel the event if inclement weather or dangerous conditions exist. If cancelled, final results will be based on completed laps at the time the event was called.

Finish Order is determined by number of laps, then time. Teams/Solo’s must complete their race within the 24 hour time limit-any laps finished after the 24 hour time limit WILL NOT count toward the total. No laps may start after the official finishing hour. Teams and solo’s may choose to stop and rest at anytime during the event but must re-enter where they originally exited. The team/solo (in its category) with the most laps is first. If teams have the same number of laps, the team that took less time within the above guidelines, wins.

Solo’s and teams may complete their race at any time during the 24 Hrs and will be credited with laps completed to that point to determine placing. Solo’s and teams do not have to finish within the above time constraints but must ride at least 6 laps to qualify for awards.

Numbers may not be cut, folded, altered or defaced in any way. The event uses dispoable timing chips. All protests must be filed within 15 minutes of preliminary results posting. All signed, official results are FINAL. No protests will be accepted, nor will results be adjusted after the event. Athletes must be in attendance at the awards ceremony to receive their medals and prizes. Awards will not be mailed. Printed results will be overall places and lap times (but will not include specific rider times-please keep track of the laps that you ride in order to determine your lap time). Results be available on the web at on or after June 2.
