2013 Avl Du HorsesFor the French aristocrat in all of us, this rough-cut, crown-emerald of a race sweeps participants through a mystical journey, back to a time, when the estate might have resembled an 15th century countryside plantation, complete with a game-stocked forest, working vineyards, and a cold mountain river rushing by. Racers on this day will be lords of the land they claim under fast plowing feet & spokes.

2014 Asheville Duathlon Race TeeAre you ready to for a premiere event at Biltmore Estate?!  Also known as the Asheville Duathlon, this 5k road run, ~12 mile off-road bike leg, and a final 5k packed dirt foot race returns to Biltmore in the fall of 2015. Our BRAND NEW  20 mile, 40 or 60 mile Gravel Grinder Bike Race takes you off road on these historic grounds all on Biltmore Estate property. We will keep the trail runner favorite 10k Off-Road Run on the schedule as well as the popular Du 4 Kids (run/bike). Join endurance athletes of all abilities on 7:45/8:00 am on Sunday, September 11th, 2016, and step to the start line, hearts booming in anticipation, to challenge mind and body while competing in the 4th annual multi-sport event held at Biltmore Estate.

2014 Asheville Duathlon Runners at Lagoon



Congrats to you and your entire staff on a very well organized and successful event. I participated in the 60mile gravel grinder and found the course exciting, challenging and just plain fun. I felt that all aspects from picking up the packets to the finish line events were staged well, plenty of friendly people to talk to and good information.  Thank you and the entire Idaph team and the sponsors for a perfect fall day.  I can promise if I am in town again next year I will indeed sign up again.

Rob Potter, 2015 Participant

DADwaitingWe encourage athletes of all shapes, sizes, ages, and fitness levels compete in our duathlon and prove that when you put your mind to something, anything is possible. The focus is on PARTICIPATION rather than competition, and to create an unbelievable experience for competitors, family, and the greater community at large! Create an opportunity to meet friends and other youth athletes who are interested and engage in the multi-sport lifestyle; providing a great social atmosphere in which lifelong friends can be found at club events, training rides, and races. Each athlete will receive a t-shirt,  goodies, & food at the event.

Like sophisticated packs of high society fox hunters, on a never ending quintessential journey for the elusive quarry, racers can round up with their fellows and friends (in relay teams of 2 or 3) to prove their mettle or give the course a shot on their own.
