SAN FRANCISCO — Thousands of workers will head to Chase Center Thursday evening for the 40th JPMorganChase Corporate Challenge, but the practical impact extends well beyond people running the race.
The company says the 3.5-mile run/walk begins at 6:45 p.m. Thursday, Sept. 10 at Chase Center. SFMTA says the race will temporarily close streets in Mission Bay and along the waterfront and affect Muni from roughly 5:30 to 9 p.m.
If you drive, ride Muni through Mission Bay or are headed to the Chase Center area for another reason, the useful planning window begins more than an hour before the race starts.
What time does the JPMorgan Corporate Challenge start?
The race starts at 6:45 p.m. at Chase Center. JPMorganChase describes it as a 3.5-mile run/walk for company teams, with a post-race celebration inside the arena.
Registration for the 2026 race was for employees participating through company teams, so this is not a same-day public fun run. The street and transit impacts, however, affect the general public.
Which Mission Bay streets are affected?
SFMTA lists the following closures for the race:
- Northbound Third Street between 16th and King streets
- Terry A. Francois Boulevard between Third and 16th streets
- Mission Rock Street between Terry A. Francois Boulevard and Third Street
- Warriors Way between Terry A. Francois Boulevard and Third Street
- Eastbound and northbound lanes of King Street and The Embarcadero along the course area
SFMTA gives the temporary traffic-and-transit window as 5:30 to 9 p.m. That window is the best one to use when planning around the race. It should not be read as the official finish time for every participant.
How does the 15 Bayview Hunters Point Express change?
SFMTA says the 15 Bayview Hunters Point Express will reroute around the event area between 5:30 and 9 p.m.
For inbound service toward downtown, buses run the regular route to Third and 16th, then divert via 16th Street, Fourth Street, King Street and Third Street before returning to the regular route. The stop at Third Street and Warriors Way is missed; SFMTA points riders to Fourth Street and Gene Friend Way as an alternate.
Check SF News Today’s live transit page before leaving because real-time delays can outlast the scheduled reroute window.
Will the T Third and N Judah still run?
Yes, but SFMTA says both the T Third and N Judah may experience delays near the racecourse.
That matters because both lines are common ways to reach Mission Bay and the Chase Center area. If you have a timed appointment or connection, build in extra time rather than assuming the trains will move through the district on a normal Thursday-evening schedule.
Should you drive to Mission Bay Thursday evening?
If your trip can avoid the race footprint between 5:30 and 9 p.m., that is the simpler choice. The closures cut across several streets drivers normally use to move between Mission Bay, the waterfront, Oracle Park and the Bay Bridge approaches.
If you must drive into the neighborhood, do not rely on being able to cross Third Street, Terry A. Francois Boulevard or the waterfront course exactly where you normally would. Follow posted detours and allow time for traffic to stack up on streets outside the closure.
What is the best way to get to Chase Center?
For race participants, JPMorganChase lists Chase Center as the event site. Muni remains the most direct public-transit option, but the event itself can slow nearby service.
People coming from BART can transfer to Muni downtown or use other regular Mission Bay connections. Because the race occupies streets around the arena, a transit trip that avoids parking and detour hunting is likely to be more predictable than driving to the immediate Chase Center blocks.
