Start Times for Each Wave

Instead of one big start with all 50,000+ people taking off at once, we divide everyone into about 100 waves. Waves start with the fastest runners, then go to slower runners, then joggers, then walkers. Be sure to give yourself enough time to park and get to the Start Line.

The Wheelchair Pro Race starts off every BolderBOULDER right before the “A Wave” at 6:50am. Come early to watch them fly through the course at an unbelievably fast pace.

The International Pro Race starts at 11:15am, but more importantly finishes around 11:45am. Join us at Folsom Field to cheer them down the home stretch! And then stay for the grand finale, the Memorial Day Tribute, which starts at high noon.
