Selling one Groupon for a race entry for The 5k Neon Run in Pleasanton on the March 1st. Price is $19.

"The Neon Run brings the age-old traditions of running competitions into the 21st century, using a 5K course built around glow stations, from which a water-based formula rains down on runners. The liquid radiates light; coupled with the black lights and LED along the route, it creates a surreal confusion of color. The race culminates in a Neon Festival, in which each runner is armed with a personal bottle of glow paint or powder."
