August 22, 2025 - 8pm

Loved by NYC's most therapy-avoidant runners

The Williamsburg "Bridge" is actually a subtle reference to the card game "Bridge".

How does it work?

The 2025 Williamsburg Bridge Marathon will be a random distance between 10 and 40 miles. Shortly after the race begins, our AI overlords will generate a random number between 10 and 40 miles. This number will be published X*6.5minutes after the start time of the race. The race doesn't end until you've run this distance back and forth on the bridge.

Example: if the selected distance is 32, the announcement will be posted online 208 minutes (~3.5 hours) after the start of the race.

In order to be eligible for prize money, racers must:

  • Submit a Strava file that begins at the start time of the race and completes the full distance.
  • Distance will be determined by the number of full bridge laps in the file, NOT the distance reported by Strava.

FAQs

Q: How long is the race?

A: I genuinely do not know. As described above, the race is a random distance between 10 and 40 miles. The distance will be picked by a computer and sent out to participants as they're running. I'll find out when you find out.

Q: Does everyone race the same distance?

A: Yes. (Unless you DNF)

Q: How does the course work if the distance is unknown?

A: The course is just back and forth on the Williamsburg bridge. It will repeat until the distance has been covered.

Q: Can I race as a relay?

A: Yes. Feel free to make a relay of any size and switch off as often as you'd like.

Q: Are relays eligible for prize money?

A: Yes. There will be a separate category for relays. Important: to be eligible for the prize, your relay MUST submit a SINGLE strava activity. Best way to do this is to use a running watch as a baton.

Q: How will the prize money be split?

Top relay: $201

Open Category

First: $250

Second: $100

Third: $50

Female Category

First: $250

If there are fewer than three finishers in a category, prize money will roll up.

Q: How will I get paid?

A: Venmo

Q: I don't think I can run 40 miles.

A: I think you can, so I guess it's a tied vote.

Q: Why?

A: You never know what life will throw at you, why should you know how long your Marathon will be?
