Case Study: Los Angeles Marathon achieves 30x ROI and $624K attributed revenue with AdRoll

Los Angeles Marathon - Customer Case Study

Los Angeles Marathon, one of the largest U.S. marathons drawing runners from all 50 states and 55+ countries, needed to increase registrations, re‑engage past participants, and grow the race year over year after past digital efforts produced minimal returns. Their challenge was clear: make digital advertising drive more sign‑ups and sell out sooner.

AdRoll developed emotionally driven creative and ran retargeting across Facebook, Instagram and the web, with Instagram emerging as a high‑value, less saturated channel. The campaign delivered a 30x ROI, a $6.18 blended CPA, 3,400 registrations and $624K in attributed revenue, prompting the marketing team to prioritize Instagram content for future events.
