Independent Adventures
Sometimes referred to as Hybrid or Self-Guided, these are essentially D.I.Y. events. Go out and complete the course on your own, with friends if you like, and/or with aid provided by friends.
Afterward, email in your activity link for proof of completion and you'll receive a finisher award and rank in the results.
For each of these, you will have an entire month (or longer) to get it done in. In other words, you choose when you'll run the course—it just has to be run continuously (all in one go) and within the specified time period.
