4th Anniversary Beer and Donut Hole Miles [runsignup.com]

Join us for our take on the Beer Mile and/or the Donut Hole Mile to be held as part of our 4th Year Anniversary celebration on Saturday, March 7th, 2026!

In the spirit of a traditional Beer Mile format, you'll have to drink one 12oz beer before running each quarter mile. Since we don't have a track at the Tap House, our course will be a quarter mile out and back loops alternating directions (starting eastbound) along Ralston Creek Trail. If you are looking to break the Guinness World Record you will need to look elsewhere ... but if you are the top male individual finisher, top female individual finisher or top team finisher, you will earn your spot on the Tap House Wall of Champions plaque! If your beer mile training level isn't quite there yet, grab a partner and sign up as a 2-person team and enjoy half the beer with twice the fun!

But first, we'll start with our family friendly Donut Hole Mile! Run in the same way as a Beer Mile ibut you eat progressively more donut holes before on each leg... 1 donut hole before the 1st quarter mile, 2 before the 2nd, 3 before you run your 3rd quarter mile and, of course, 4 right before you head out for the last leg of the mile for a grand total of 10 donut holes! Each runner will consume 5 glazed and 5 chocolate donut holes.

Due to congestion in the transition area, no strollers or dogs are allowed.

This family friendly event begins and ends on the track at the North Area Athletic Complex (NAAC) in Arvada with a scenic trek along the Fairmount Trail in the middle. Following the 5K there is a 50-yard Jordyn's Adaptive Dash where children with disabilities will show off their speed using adaptive equipment to walk, roll or ride to the finish line. This special event is a huge hit with spectators and participants alike.

We know you love your pooch and we're sure we would as well, but only service dogs with proper documentation are allowed inside the stadium at NAAC. For this reason, we ask that you leave your four-legged friends at home.

Packet pick-up is available on Saturday, May 16 from 3:00-5:00 at Barquentine Brewing Company at Edgewater Public Market. You may also pick up your packet on race morning from 7:45 a.m. to 8:45 a.m. at NAAC.

This is not your run of the mill 'Turkey Trot.' This is the Turkey TREK! Are you up for the challenge? Run a steady uphill climb to the summit of the course at the 3 mile mark. Poised at the top of the hill is the infamous EGG NOG CHUG Challenge where racers (have the option) to chug 5 oz of eggnog. (Those who 'chug' are entered to win a new pair of shoes!) It's windy and wild at the top and the limitless views are UNMATCHED. Run the ridge for a mile before starting the more gradual, yet still winding, descent down the east side of the mesa. Once down the hill, racers encounter a relatively flat straight-away peppered with HAY BALES for the hay bale hop challenge. Continuing the clock-wise loop back into the park, runners find the final challenge - just one kilometer from the finish: Fill Your Pie Hole Challenge. A fresh portion of holiday pumpkin pie awaits racers there. Once the pie is 'down the hatch', the joy of the finish line isn't far away. Is this a course on which to set

a personal record? Hah! This is the course to BRAG about completing - with ALL of its holiday-themed challenges. Are you ready to conquer it?

We know that some of you require a bit more training before attempting the 10k loop. 5k and 2k distances are also offered, with a small 'taste' of the full course of challenges!

For those of you who eat hills for breakfast and wash them down with egg nog on the daily, a bigger challenge is offered at the 2025 event. New this year, the HALF TURKEY!! The HALF TURKEY visits all the challenges offered to the 10k Trek runners, and adds some mileage to get you to the 13.1 mile distance. HALF TURKEY finishers receive a MUG at the finish line to commemorate their accomplishments!

The Resolute Runner 5K is the KICK OFF PARTY OF THE YEAR! It's time to be RESOLUTE, to retroactively earn your pumpkin pie and chocolate truffles, and to start the new year on the right foot, literally!

The course starts at Johnny Roberts Memorial Park in Arvada, CO, and winds through the beautiful Ralston Creek Trail. It really is quite a scenic race! As you run, all of your fans will be able to see you from the start line, then walk less than 1/3 of a mile to see you at two different points before cheering on your finish. This is a very spectator friendly venue and a great way to kick off the New Year!

Be a part of our community-based race as we partner with Community Table to restock their cupboards after a busy holiday season.

Join a team of 5 or more and everyone saves $5! See our FAQ page for more info!
