Second Leg of the Madison Trifecta​ 

The original Madison Duathlon (a bike/run race) started out as a natural expansion of a good idea (i.e. the Madison Marathon), but it quickly became a good idea on its own.  It was an A to B that started in Ennis right near the banks of the Madison River and then went up and over the mountains to Virginia City.  It was a great route and many duathletes who have competed in the Madison Marathon say they had more fun on the duathlon.​

The start is at Lion's Club Park in Ennis. The first run will essentially be a sprint of sorts.  We will shuttle you three clicks away from the park and then say 'Go.'  Everyone runs back to the park and gets on their bike.  Then, the cycling route heads out of town and towards Axolotl Lakes.  There are two big-ass climbs.  The second one takes cyclists out towards Highway 287 and then returns.  The bike/run transition is near Axolotl Lake.  Then, runners go down a valley towards Virginia City.  This is a 10K run with the finish line in Discovery Park in Virginia City. 

The duathlon is the second leg of the Madison Trifecta.  The first leg is the previous day (Madison Triathlon), the second leg is this duathlon, and the third and final leg is the following Saturday with the Madison Marathon. 

You get all three races in, and you're a TBA - Total Bad Ass!

If you get just this duathlon in, you're a bit of a bad ass as well.  At the very least, you get to participate in Montana's only Olympic duathlon.  That alone is pretty bad ass!

See you in July!
