About AERC Mileage Challenge
In an effort to make AERC activities accessible to ALL members, the AERC 100 Mile Challenge was created. Ride at your own pace, in the location of your choice, for 100 miles over ten weeks. Record your time and mileage after you complete each ride. There is no minimum, or maximum daily mileage, but you must maintain your mileage logs and ride in a prudent manner, putting the health and wellbeing of your equine partner first. There will be prizes for all who complete 100 miles and the Top 5 teams with the highest mileage by the closing of the ride dates in both the competitive and non-competitive categories will receive additional awards.
