Endomondo is a (free) web service that keeps track of your workouts, and allows you to interact with other users. First, you create an account online. Use the "settings" to choose whether you want to keep your workouts completely private, make them visible to "friends" only, or visible to all. You can add a workout by hand on the webpage by drawing the route you've ridden on a map. You can add your start and end time as well, and choose your type of exercise ("Riding"). The "statistics" tab allows you to view a summary of your past workouts, for example each month's total ridden distance - very convenient for The Long Ride.
If you own a smart phone, you can download the free Endomondo app. If you activate and stop the app before and after each ride, your ridden distance, time, speed, elevation gain etc. will automatically be uploaded to your web account. This way, you don't have to enter each workout by hand.
For extra fun, you can issue or participate in "challenges". For example, there's a challenge running for The Long Ride, which will count each participant's distance ridden from August 4th until next year, and shows who is in the lead. If you decide to sign up, search the Challenges, using the pull-down tab to restrict to "Riding", and you'll find The Long Ride challenge. Then click "Join". The more the merrier! .
