It's the world's shortest race, dubbed Philadelphia's first ever Instant Gratification Run.
Unlike the Philadelphia Marathon, where thousands of runners stare down the challenge of 26.2 miles, in this run the start line is also the finish line.
Runners need to only step over it to both begin and end their 0.0 mile challenge.
All participants are then invited join in the post-race festivities.
The race steps off on February 6 in South Philadelphia at 7:30 p.m. and promptly ends one second later.
Registration for the Philly 0.0 Instant Gratification Run is $35 and all proceeds benefit charity.
