5TH Annual
The 5th Annual Mackyard Ultra presented by Baltimore Road Runners Club is an ultra and running race on October 31, 2026 in Cockeysville, MD, with an entry fee of $25.
From the Organizer
The Baltimore Road Runners Club is thrilled to bring a sanctioned backyard ultra to the Baltimore running community by partnering with race founder Mac McComas to present the 5th annual Mackyard Ultra!
For those unfamiliar with backyard ultras, it is commonly referred to as a "last man standing" event. Runners will complete a 4.1667 mile course each hour until one person completes a lap (called a yard) by themselves. That person is the winner and only finisher of the race.
The race will take place at Shawan Downs on their cross country course, so be ready to run on grass with plenty of ups, downs, twists, and turns to keep you engaged on each out and back lap.

This race spans more than one sport — here’s a guide to each, so you can understand what’s involved and decide if it’s the right fit. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
An ultramarathon is anything beyond the standard marathon — 50K, 50-mile, 100K, 100-mile, and timed events. Crossing the line is less about speed and more about not quitting.
From 5K to marathon, running races are an accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
