Fall is a season that recalls falling leaves, family gatherings, and (at Buttercup Ranch) the anticipation of fresh cider from a homemade press.  It was an obvious theme for our race when our son Josh asked, "Why not have a triathlon at the farm?"  Since it is held annually around 9-11, we donate 20% of sales to our local first responders in memory of John Ogonowski, captain of Flight 11.  10% goes to Millstadt Fire Department.  10% goes to Millstadt Police.

The 40/50 Mile Challenge is a continuous loop endurance race designed for runners who want to push beyond traditional race formats while benefiting from a fully supported, centralized course.

Held alongside The Next Loop Endurance Series, this event runs on the same 3.1-mile (5K) loop, but unlike the hourly format, competitors in the 40/50 Mile Challenge run continuously with a strict time cutoff.

What Is The Next Loop?

The Next Loop Endurance Series is a loop-based endurance running event designed for every type of runner — from first-time 10K participants to seasoned marathoners, ultra runners, CrossFit, Hyrox, and tactical athletes.

This triathlon is a welcoming and fun experience that introduces the sport to first timers and developing triathletes. We time and score this event- but don't have awards in the traditional sense- everyone who participates wins. The Tour de Kirkwood Title Sponsor- Heather G. Johnson Realty will be providing a post-race lunch by Blues Fired Pizza's food truck! Come for the race and hang out and cheer people as they finish!
