Rollover Credits

If you cannot participate in an event for which you have registered, you may be eligible to receive a Rollover Credit, which may be applied towards any future Enviro-Sports event. Rollover Credits may be applied toward any Enviro-Sports event(s) at any time – there’s no expiration on your credit. To retain a Rollover Credit, you must notify us of your intention to pull out of a race NO LATER THAN 30 DAYS PRIOR TO THE EVENT DATE.

If within the 30 days leading up to the event a medical reason, military deployment or death in the family will prevent your participation, you must notify us in writing and attach documentation (i.e. doctor’s note, deployment notice) to support your claim. We must be in receipt of your written notice at least 72 hours before the published race start time. All requests for Rollover Credits for any reason besides medical, military deployment or death within 30 days of race day will be denied.

No credits will be issued within the last 72 hours prior to race start. A Rollover Fee will apply for all Rollover Credits (See chart below).
