About this race
You’re In. Welcome to UltraTrax Philadelphia.
On September 25, 2027, you’ll take on a full day of movement, challenge, and time on the trails at the Schuylkill Center for Environmental Education in northwest Philadelphia.
Founded in 1965, the Schuylkill Center is one of the country’s first urban environmental education centers, with 365 acres of forests, fields, streams, ponds, and protected open space. Your course winds through mature tulip poplars, oaks, beeches, quiet woodland, and art installations that make this one of the most unique UltraTrax settings on the calendar.
Whether you’re here to walk 7 miles or push all the way to 28, the challenge is yours to define.
10 hours. One 7-mile loop. Four distances. How far will you go?
Complete your goal within the 10-hour event window. Want another layer of challenge? Take it on with a 10, 20, or 35 lb. ruck or weighted vest.
The course will be clearly marked from start to finish, with well-stocked aid stations positioned along the route to keep you fueled and moving.
Trek Day
Saturday, September 25, 2027
Schuylkill Center for Environmental Education
Philadelphia, Pennsylvania
The start line is open between 7am–10am and is divided into corrals based on distance. 28 milers get started at 7am, 21 milers at 7:45am, 14 milers at 8:30am, and 7 milers at 9:15am.
UltraTrax is not a race, but it is a timed endurance event. You’ll have up to 10 hours to complete your chosen distance.
Move at your pace. Take breaks when you need them. Then keep going.
Bib Pickup
Your bib may be mailed to you in advance or picked up on event morning.
Participants registering after September 5, 2027 must pick up their bib in person. A friend or relative may also pick up your bib for you.
Taking on the Ruck Challenge?
If you registered for a weighted division, you’ll need to bring your own ruck, backpack, or weighted vest.
Your pack will be weighed before you begin. Everything in the pack counts toward your required weight except perishable food and drinks.
What’s Waiting at the Finish
Finishers will receive:
- A custom UltraTrax finisher medal (Grey Wolf Medal for 28 and 21 milers, Trail Wolf Medal for 14 and 7 milers)
- UltraTrax event T-shirt
- UltraTrax patch
- Additional swag for weighted divisions
After your trek, stick around and enjoy the fun atmosphere. Food and drinks will be available for purchase, with space to recover, refuel, and celebrate with other participants.
Friends and family are welcome to join.
What to Expect in Philadelphia
An Unexpected Escape Inside the City
Just minutes from the heart of Philadelphia, the Schuylkill Center feels worlds away. The course moves through deep woods, open fields, streams, ponds, and quiet stretches of trail across 365 acres of protected land.
A Course Full of Character
Expect mature tulip poplars, oak and beech forest, rolling terrain, woodland paths, and art installations tucked throughout the property. This is a course where the scenery changes constantly as you move through the landscape.
A Challenge You Choose
There is no single definition of success at UltraTrax. Walk your first 7 miles, chase 28, or add weight and see what you can carry.
Support Along the Way
Expect a well-marked course, stocked aid stations, event staff, and a community of people working toward their own goals alongside you.
Parking & Shuttles
A limited amount of VIP parking is available onsite at the Schuylkill Center.
Complimentary event shuttles will operate throughout the day between the start/finish area and the offsite parking lot at 161 Washington Street in Conshohocken, approximately 10–15 minutes away.
Participants may also be dropped off directly at the start area.
More detailed shuttle schedules, arrival instructions, parking information, course details, and event-day logistics will be sent as Trek Day gets closer.
Move With Purpose
UltraTrax is all about spending more time outside, moving farther than you thought you could, and helping protect the places that make those experiences possible.
For UltraTrax Philadelphia, a portion of event proceeds will support the Schuylkill Center for Environmental Education and its work to protect and care for this incredible urban natural space.
You’re officially part of the pack! We’ll see you in Philadelphia.
