Thanks for the response. That's somewhat close to what I have now with SportsEvent (and Org as the sponsor), but even if I just make it a plain 'ol event, Google still complains about the lack of performer.

Anyone have bright ideas for which schema.org type to use for something like a run/walk fundraiser? Ive been using SportsEvent, but that's really more fit for, "I'm buying a ticket to watch the team play the football game at the stadium."

What we're trying to do is sign folks up to create their own fundraising webpage, then show up at an event. Google wants ticketed events to have a performer, but this is more like RSVPing for a party. Events and products feel a bit like a round peg in a square hole, but Website seems really generic for everything going on in this kind of site.

At the same time, participants are creating fundraising pages...yeah it's related to a location/time-based event, but visitors aren't really buying tickets to watch that runner "perform," they're donating to a non-profit to fight cancer. And think about applying the fundraiser to a non-sports event (e.g. donate your birthday, grow facial hair, be a secret santa, etc). Or a donation drive...those might have a product attached (kickstarter), or the giving itself might be the "product" (gofundme).

Thoughts? Here's what I've mapped out at the moment, but I don't know how I feel about it.
