Sonic Endurance offers professional race directing services for running and multisport races in Connecticut. We currently provide logistical and production expertise for the following:

Greater Hartford Quarter Marathon


The Greater Hartford Quarter Marathon features the tagline “You Should Try Other Distances.” Slightly longer than a 10K at precisely 6.55 miles, this race features two laps around the rolling West Hartford/Farmington Reservoir’s Red Trail. The race take places the first Saturday in April. It also typically features an Easter egg hunt for the smaller spectating crowd, with hundreds of eggs spread across the registration field.

Hogsback Half Marathon


The Hogsback Half Marathon, hosted on the 4th Saturday of September, is a perfect way to cap off a summer of training. Featuring a net elevation loss on this certified 13.1 mile course, the RRCA State Championship Half Marathon field is sure to push you to your best time. This race also features a first-timer friendly early start to participants anticipating to run a time slower than 2:45. And don’t forget the feast at the end!
