An interview with 2018 Afton 50KM men’s champion and new course record holder Justin Grunewald (JG) – Interview conducted by Kevin Langton (KL)


KL: Justin congratulations on an incredible race. You won by 45 minutes and blasted Chris Lundstrom’s solid course record by over ten minutes, not a bad performance for your first trail ultra. What was your plan and how did your race play out?

JG: I actually attempted a 50k in San Francisco last fall but took a wrong turn about half way through and dropped out. For Afton I had 3 goals. 1) Finish the race no matter what. 2) Win. 3) Set a course record. The race was harder than I thought it would be but the volunteers and aid stations helped me to push through to the end. I got out a little too hard and died the second half. I had only seen the first 5 miles of the course before the race so I didn’t know exactly what I was in for.


KL: How did you handle running solo out there?

JG: Running solo was fine. The second loop I had a lot of 25kers around and aid stations every few miles kept me focused.


KL: I read that you’ve been doing your hill workouts on a treadmill. What best prepared you for Afton and a trail ultra?

JG: Honestly, I wasn’t super prepared for the downs but I had been doing multiple minutes up to mile hill repeats on the treadmill at 6-10 percent grade which helps with the ups. By the last couple hills there was definitely some power hiking as my hamstrings basically stopped firing. My long run leading in was only 17 miles, which was less than ideal to prep for the distance. My coach, Mario Fraioli, has really helped with mindset, nutrition, and tackling races even when the prep is not ideal so that has also really helped.


KL: What’s something non-running that helped you at Afton?

JG: Whenever the going gets tough I reflect on my wife and the battle she/we have been through the past years and it always somehow makes the race easier. She started a nonprofit this past year, Bravelikegabe, to raise money for rare cancer research and help empower, inspire people going through rough patches to stay active. Whenever something starts to hurt or thoughts of doubt creep into my head during a race, run, or everyday life I try to think Bravelikegabe and it makes it easier. (Editor’s note: for more info see https://bravelikegabe.org)

KL: Do you have more plans for trail running in your future? What drew you to Afton?

JG: Long term goal is Western States. Hoping to move up to 50 miles this fall. Afton brought me in due to proximity to my home in Minneapolis and stories I had heard about what a great race it is. I had actually only run there 3 times but it seems like the ideal place to put in long trail miles in the area so I plan to head out there weekly to get some time on foot.


KL: Your wife, Gabriele Grunewald, has had several battles with cancer, something she’s been very public and inspiring with, especially as she runs through it all. Would you care to share any updates?

JG: Big updates are she has a few mile races on her schedule this late summer and fall and she is starting to kick my butt on the track again so I know she is getting fit.

KL: Anything else?

JG: I just want to thank John for putting on such a great race and inspiring the trail culture in Minnesota. I also want to thank all the volunteers for being so awesome out there. I had no shot at the course record without their help at the aid stations.

More About the Race / Area:
The Afton Trail Run is one of the most challenging and beautiful trail races around.  The race was established in 1994 and is now one of the oldest, largest and most competitive trail races in the country and routinely draws runners from all 50 states and beyond.  The race takes place entirely within the borders of Afton State Park.  Afton State Park lies on a glacial moraine, scribed with deep ravines running down to the St. Croix River.  The 169 mile St. Croix River was one of the original eight United States rivers to have significant portions placed under protection by the National Wild and Scenic Rivers Act of 1968.  Within the park sandstone outcrops have been exposed in some of the ravines. The vertical drop from the blufftop to the water is 300 feet.  A few patches of remnant prairie survived the decades of farming that took place on the blufftop. Today the former fields are being restored to prairie and oak savanna. The ravines leading down to the riverbank are thickly wooded with oak, aspen, birch, and cherry.
