Participants do not need to come to you for platform questions. Race Space runs its own participant help centre with articles covering everything a participant can do on the platform, such as actioning a transfer, finding their ticket or registering an entry after a Speedy Checkout purchase.
The help centre is at help.race-space.com.
Alongside the articles there is a support messenger where participants can get an answer directly from Race Space. Most questions are answered there without anyone contacting you.
What still comes to you
Race Space handles the technology. Anything about the event itself remains yours: the route, the start times, what is included in an entry, whether you will make an exception to your own refund policy, and anything else that is a decision rather than a platform question.
Participants are pointed to you for those, so the split works as long as your event page carries the practical information they need.
