Cinco Du Mayo

Short and Long Course / Saturday, May 6th, 2017 / 8:45AM / Square Lake Park, Stillwater, MN


The Multi-Sport season begins early with Tri Fitness. Cinco Du Mayo is a Duathlon: a Run-Bike-Run event held at Square Lake Park in Stillwater, MN.

Now, before you start reading too far into the name of our event, let us clear a few things up. We are not commemorating the Mexican army's unlikely victory over French forces at the Battle of Puebla on May 5th in 1862...with a Duathlon.

As happy as we are for General Ignacio Zaragoza Seguínwe and his army of 4,000 decisively crushing the (8,000 strong) French army, the best army at the time - and might we add, one that had not been defeated for almost 50 years (thanks Wikipedia!) - we really don’t see much connection between the two, so that would be weird. This event isn’t even held on May 5th every year. It’s held on the first Saturday in May, no matter the date.

Here’s how it really happened: We have a race in early May. This race happens to fall somewhat close to Cinco De Mayo. the "De" sounds a lot like "Du" (you can see where this is going...) which is what Multi-Sport athletes say when they don’t want to expend the extra energy to articulate two more syllables (a true Multi-Sport athlete saves energy whenever they can!). Thus was born the, Cinco Du Mayo.

So we race. And then we eat tacos...tasty, tasty, tacos.

Fat Bikes are welcomed to this event.

Course Profile

You are responsible for knowing the course, so please study the maps and directions. We'll have volunteers on the course, but still...please know your stuff.

Both courses include an "out-and-back" run that starts within the park but keeps the majority of the distance on the scenic avenues outside of the park boundaries. The short course is a 2 mile run, 10 mile bike, 2 mile run. The long course is a 3 mile run, 20 mile bike (two loops of the short course) and 3 mile run.

The bike course for this event features rolling hills that traverse through some of the most beautiful terrain in the Stillwater area. The short course is great for beginners, while more seasoned duathletes will find it to be moderately challenging.

The long course features double the amount of rolling hills (2 loops on the bike course, etc.), and just seems to be a little more demanding. The weather in early May is often cool - the longer exposure times for the long course athletes can take its toll. Please dress accordingly.

Run Course

Both runs begin within the park, but make their way quickly to the roadways outside of the park. Runners take a left out of the park and head left on Paul Ave. Runners continue straight until they reach the turn-around point (approx. 1.0 mile for short course and 1.55 miles for long course) and then head back to the start/transition area. Long course athletes, DO NOT turn around at the short course turnaround marker! You have another 1/2 mile or so to go.

Fluid replacement (water and HEED) will be available at the turn-around point for the short course.

Run/Bike Transition Area

To help with the congestion that often happens within the transition area, only participants and volunteers will be permitted in the transition area. Bikes must be walked/run in the transition area. Mount/Dismount Zones are located just outside the transition area. You must wear a helmet while with your bike. For teams, please transfer your chip at your bike transition area.

Bike Course

The Bike section of this course follows a clockwise route around Big Carnelian Lake and Little Carnelian Lake. Participants will begin the bike course by leaving the transition area and taking a right out of the park on Square Lake Trail N. Directional signs, mile markers, and volunteers will be posted on the course during the race to assist with navigation, but it always helps to know your course.

Remember, Long Course athletes make a second loop around the lakes before heading back in to transition. Please consider giving these maps a look ahead of time, or even better, give it a ride, and you'll be good to go on race day. Short Course athletes only do ONE LOOP of the bike course - know when to head back, check the map!

The entire bike route is open to traffic, so please be aware of vehicles and plan on following all traffic rules when traffic control is not present. The road surface is asphalt and course volunteers (armed with brooms) are stationed at all turns. This should be a nice, clean course, so please help us keep it that way by holding on to your empty gel packs or other litter. All bikes are required to display a bike number.

Tri Fitness and Penn Cycle will provide pre-race and on-course bike support.


The finish area is located on the road, inside the park, adjacent to transition area. Volunteers will assist in removing race numbers and/or timing chips.

Bottled water and post-race tacos will be provided. In order to keep them as warm as possible, the tacos should arrive by 10:30 or so.
