Our most effective tool for getting more people to your race is a ‘Boost’. Boosts put your event to the top of the search results.

Typically a Boosted event gets 8x as many Impressions, 4x as many Clicks and generates 4x more revenue than a standard event listing.

Choose to Boost your event on the landing page which best suits your target audience and budget. For example, ‘10k’s near San Francisco or ‘marathons in April’. Our team can advise on scheduling promotions to optimize performance.

Prices start at $100 per month. The most popular categories sell out in advance so booking early is recommended.
