Virtual Events:

Hedgehog Hustle

With so many events are cancelled and so many of us are reeling from the loss of community these races provide, we wanted to do something to help build back the community we’re missing. What’s our solution?  It’s a virtual race, but with a bit of twist — the choice of a progressive half marathon, marathon or 50 miler over the months of October and November (or in hedgehog parlance an array of options for runners of all abilities).  Beneficiaries of the Hedgehog Hustle are Running for Rescues, Ainsley’s Angels and Love Your Brain.

Planks and Thanks Challenge

Two weeks of core work and gratitude exercises that allow you to reflect on good things that happened in 2020 while strengthening your body for what lies ahead in 2021.  As we believe strongly in giving back to our communities so a portion of the proceeds will be split between Knox and Manna on Main.


Road Races: 

Sonic Endurance offers professional race directing services for running and multi sport races in the north east. We currently provide logistical and race 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!
