You may choose from 10, 25, 40, 65 or 100 mile routes. Please note that fundraising minimums vary based on your selected distance, and that published mileages are approximate. We may call one route 40 miles but in fact that true mileage may be closer to 39 or 41 miles. Mileage is calculated via odometer in a vehicle, which will always differ from a bike computer, and doesn’t include additional riding such as in to and out of rest stops.
