Hennepin Healthcare Field Day & Surly Brewing Co. Trail Loppet

The Urban Trail Run and Festival
Half Marathon · Half-Half · 5K

The Hennepin Healthcare Field Day on Saturday is a fun-filled day of both competitive and non-competitive events for all ages and abilities. The day will start with a timed 5K trail run/walk and be followed by an untimed 1 mile and 0.5 mile trail run, before concluding with a variety of fun “trail and field” games and challenges.

Our most popular trail running event of the season, the Surly Brewing Co. Trail Loppet on Sunday is a day of rugged, urban trail running in Minneapolis’s largest regional park. The Half Marathon and Half-Half (6-8 miles) races in Theodore Wirth Park are the ultimate urban trail running experience, and all participants will be greeted after the race with music and a free Surly Brewing Co. beer (with a valid ID).

Aid Stations

Aid stations will have water and energy to keep runners hydrated on the course.

Cut-off Times for Sunday’s Half Marathon and Half-Half

Racers may choose to finish, but course marshals and volunteers located at and before the 45 North Aid Station (mile 9 of the Half Marathon and mile 3 of the Half-Half) will be released from their positions at 12:00pm. There is no cutoff for the 5K or youth races. We set these times to be sure our volunteers aren’t out all day long but all participants still have plenty of time to finish.

Transportation, Parking and Bike Corral

We encourage participants and spectators to bike, walk, or jog on race morning. There will be a monitored area at the Start/Finish where you can check in and/or lock your bike to racks.

For those who must drive, we encourage carpooling. All participants and spectators should park in the nearby Mortenson parking lot. We expect the Trailhead lot to fill quickly. It is a short walk or jog from the Mortenson parking lot to the start area. Please do not park in any reserved spaces at Mortenson.


Participants must register by Sunday, September 4th in order to receive a race shirt . If you register after the 4th, please check at packet pick-up- there may be some shirts available in select sizes.


Awards will be given to the top three overall men and women in the Half Marathon, Half-Half and 5K.

Results will be listed for age groups as follows 19 and under, 20-24, 25-29, 30-34, etc.


All registrants will be entered to win a 2-night stay at the beautiful Heartwood Resort in Trego, Wisconsin — perfect for your outdoor adventure getaway. Two participants from the Half Marathon, Half-Half, and 5K will be randomly chosen and contacted after the event.
