The following is from ORRC Dual Duel volunteer Race Director Daniel Brewer:

ORRC has consulted with medical professionals, and despite any amount of cooling preparations we have arranged, it will simply be unsafe to hold this event in the excessive heat forecast for race day.
The event will now take place at the same time and venue, on Thursday, August 10th, at Catlin Gabel School, with the ORRC Mile heats beginning at 6:00 pm and the Dual Duel and 10k at 7:00. We will still finish under the lights around 9:30.
While we would love to see every participant on the new date, we know that will not be possible for everyone; therefore, ORRC would like to offer registered participants one of the following three options:
- Participants may run as planned on the new date.
- Participants may choose to have their registration deferred to another ORRC race of their choice up to a 10k and before August 31, 2018.
- Participants may request a refund.
We appreciate your patience and understanding. I look forward to seeing you at your next ORRC event.
