49ers Rush is a first of its kind endurance event that takes place at Levi’s® Stadium and the 49ers SAP Performance Facility. You can select to participate in either the 4.9k Stadium Run or, if you’re up to it, you can take The Challenge. The 4.9K Stadium Run will be a race through the stadium and practice facility with light stair and ramp obstacles. The Challenge will be more intensive. Just finishing will be an accomplishment. You must complete a 4.9 kilometer course of stairs, ramps, and many of the football obstacles and drills we use to prepare the team for gameday.
