    Beaverdam Reservoir Park | March 8 | Starts at 8:00 AM

    To celebrate International Women’s Day, I’m hosting an Endurance Celebration—a choose-your-own-challenge day centered on movement, support, and showing up exactly as you are.

    Beaverdam Reservoir features a 7.5-mile loop with roughly 300 feet of elevation gain, circling Beaverdam Creek. The course is beautifully varied: a mix of fire road and singletrack, more rugged forest trail on one side, and more developed sections with boardwalks on the other. It’s approachable, interesting, and perfect for settling into a rhythm.

    We’ll begin together at 8:00 AM, and for anyone who wants to do multiple loops, there will be support available all the way until sunset. The goal isn’t speed or comparison—it’s choice.

    This day is for you if:

    🎯 You’ve been nervous to try a bit more distance

    🎯 You want to test new gear or nutrition

    🎯 You’re returning after injury, rehab, or a long break

    🎯 You want a safe, supportive environment to see what your body can do

    🎯 You simply want to support other women

    You’ll have course support, including:

    ✅ Snacks & electrolytes

    ✅ Water

    ✅ Basic first aid supplies (bandages, moleskin, etc.)

    This is a free event.

    This event centers women, but men are welcome to volunteer as course support—I’ll need a few helping hands.

    If you would like to support or partner with this event, I’d love to hear from you (especially if you’re a women-owned business or a nonprofit that serves women).

    Important notes:

    Participants are responsible for their own risk.

    If winter weather is possible, I’ll scout the course the week prior to confirm conditions and ensure we’re good to go.

    The Bull Run Run is a 50 mile trail run within a linear park that generally parallels the Occoquan River and the famous Bull Run in southern Fairfax County, Virginia. It traverses a forested, rolling terrain during the height of the state's spring beauty. The run’s unique character includes a Civil War theme that honors the battles that occurred here over 150 years ago. A highlight of the race course are the stretches that take the runners through the largest bluebell stands on the East Coast. The 2026 race will be the 32nd running of this classic event.
