Virtual Padden Mudfest

Mon March 1, 2021 to Wed March 31, 2021 – Virtual

The 2021 Padden Mudfest Virtual courses are the same loop courses as last year. This year, both the 5K and 10K start and finish at the trail kiosk.

There is a 5k option as well as a 10k option. The 5k course is essentially the second half of the 10k course, and the 10k course is significantly different from the course that has been run in past years. Both courses are hilly, going up and down the trails on the hills surrounding the lake, though both finish with a flat lakefront run along the exposed and scenic shores of Lake Padden. The course maps can be viewed below.

Race Description

The Padden Mudfest is a trail run that takes place on the horse trails around Lake Padden in Bellingham. If you have not run the horse trails yet, you are in for a rooty, rocky, and muddy treat! There are aggressive climbs, twisty single-track, and more than enough dramatic scenery to hold your attention. From the winter into early spring, the horse trails are full of slippery mud and a fair amount of water over the trail, which makes it the lovely Mudfest that we relish! This year’s theme is the Mudfest Monster. (The junior cousin of the Blanchard Beast.) Beware of the muddy areas– they will pull your shoe right off and devour it! Slip and splash into an avalanche of mud. (Clean change of clothes not provided this year!) Defeat the Mudfest Monster this year, on your own time, March 1st – March 31st and be eligible for prizes. Run it multiple times and give us your best time. The first time you run it is an eye-opener. Subsequent times, and you’ll just get faster as you get to know the course and anticipate the ever-variable conditions.

Submit your muddiest post-race pictures for a prize to our Facebook page for our photo contest. We want to see your muddy shoes and attire!

Note about footwear: We recommend trail shoes, which can be purchased at our local neighborhood running stores, BBay Running and Fairhaven Runners. (Your race director loves her waterproof Altra Lone Peaks and Timps!) Please support your local running stores, they have all the gear we need, and they support our incredible local running culture. They are passionate about our running community, and we wouldn’t be where we are as a running club without them!

Course Description

The virtual race begins and ends at the dog park side at the eastern (golf course) end of Lake Padden. Please begin and end your race at the trailhead sign.

The 5k course begins with a steep climb up to the ridge that forms the southern edge of the lake basin. It then goes along the ridge, with some potentially very muddy stretches. After a few ups and downs, there is a steep descent to the lakeshore at the point where the creek exits the lake.  A brief excursion down the gorge leads to a short rise into the woods behind the western end of the lake, from where the course emerges onto the lakeside and heads to the finish.

The 10k course starts with a 5k loop over the hill behind the golf course. This first loop begins with an only moderately steep but very long and sustained climb to the high point of the race, followed by a long and winding descent with some steep and potentially very muddy and slippery parts, especially near the end.
