I am a Trails Coordinator in my city. I would like to create a contest for people to ride/run/walk a certain segment of trail. Each lap they do can count as a point, and perhaps the fastest time can count as some amount of bonus points. Each point is equivalent to an entry into a drawing, with the grand prize and a few secondary prizes being awarded at the end of the month. I want to do this for each month, rotating through some of our trails that don't see as much attention in order to help motivate folks to use them. If you completed the contest each month, you're eligible for a big end-of-year prize.
In order to accomplish this, I need athletes to opt-in somehow (so only people aware of the contest are eligible for prizes), and I need to be able to see all of the opted-in athletes that completed the task, how many times they completed the task, and who did it fastest.
It seems like the type of thing a "Challenge" might be able to achieve, but there's no avenue for me to create one of those as far as I can tell.
Does anyone have any pointers on how I could pull something like this off? I'm sure similar contests have occurred elsewhere! Thanks so much.
