As I understand it they are technically not connected.
You ride the ToS in the SYSTM App and get the badge if you stay in the 50h windows for each workout.
You fundraise on the DPF site and may win something.
The first is a great way to advertise the second. You may even win something from the DPF fundraiser when you did not complete the ToS. You just don’t get the badge in SYSTM. (That would be 1. The Money-Raising Option from here)
The couchlandrians may try to trick you into riding the ToS in SYSTM and get the badge without fundraising. But beware the wrath of Grunter, , the and the Minions!
The two are connected through our hearts and the great mythical Nation!
