When we announced the Strava partnership with races using RunSignup last year, we had a number of races who really emphasized the linkage of the race to the training leading up to the race. This benefited participants and the race by highlighting the fact that the race was about more than just race day.
We recently changed the Strava sponsorship to be an opt-in rather than an opt-out for new races. We also are changing the revenue share to be greater than 100 new Strava users to earn the sponsorship revenue since the processing overhead for smaller races was to burdensome. However, we still suggest you take advantage of this as Strava helps add brand value to almost any race.
