Lake Macbride Trail Races

Lake Macbride Trail Races!

Carrying on the tradition of wonderful races run around Lake Macbride, this is a moderately challenging, one or two looped course event focused on some of the best trails at beautiful Lake Macbride State Park, the largest State Park in Iowa.

Course Description

This event starts and finishes at the Macbride Spillway parking area. Runners will start by running the North Loop, which is mainly crushed limestone trails adjacent to the Lake. These early miles will lead to an out and back on the North Shore trail where the first aid station is located. Then things start to get technical on the North Snowmobile trails. This will lead back to the start/finish aid station, before crossing the dam for the first Spillway crossing and the South Loop. The South loop will provide runners with a variety of terrain, as there is single track, prairie, and some fun hills to keep things interesting. The final aid station will be at the Anglers Point lot, before the return trip back to cross the Spillway a second time, and finish the loop! 50k runners will then go back to have some more fun on a second loop!
It is important to note that runners that were familiar with the previous race that was run at Lake Macbride, will find a very different course than had been run for the last decade of that event. The planned LMTR route is nearly all on trails and avoids running on any major sections of road/highway.

Volunteers are the lifeblood of local trail races. It takes the whole community to pull off an event of this scope, and it would never happen without volunteers. If you are not able to run the event and would like to be a part of race day, we would love to have you join our volunteer team to assist with event set up/takedown, packet pickup, sag runner, or the all important aid station volunteers that keep our runners fed and hydrated! Volunteer link is open! Get your friends and family involved on race day!
