The free future race is good for any Continental US Sprint, Super, or Beast. If you volunteer at a Sprint, you can use your free race at a Super or a Beast, and vice versa.  The Free Future Race registration works as any other registration.  You can sign up with a team and choose the time block you want to race in. You will just need to pay the $14 insurance fee and a small processing fee.

The free race from volunteering at a Sprint, Super or Beast is not valid for specialty events including but not limited to Charity Races, Ultra Beasts, or Agoges.
Volunteers at the Agoge will receive a free future Agoge entry.
