For the last 3 years I’ve created a challenge for my friend group (both individual and group). One year it was to run 1000 miles (individual challenge), another year was to complete 1000 hours of activity (individual challenge), and this last year was to run/walk/bike/board/etc the circumference of the globe (group challenge). Goals are limited to time and distance. I would love to have more options to create those challenges. For example, the most PRs in a year, the most different activities participated in a year, the longest streaks in a year, etc.
