Lake Fairfax Course Description

Located in Reston, VA, Lake Fairfax has a beautiful lake and an awesome trail network. Our courses hit the best singletrack and include some great views of the lake. There are a few short technical sections (more rocks and roots), but most of the course is relatively smooth singletrack. There is barely any pavement on this course. There are no extended climbs, but lots of short ups and downs.

Little Fern Learning race day kids program

Little Fern Learning Kids Program

Little Fern Learning offers fun and engaging race day programs for your children while you are racing. Sanna Adams will spend the morning exploring the nature that area parks have to offer, engage in fun STEM activities, cheer on the grown-ups and participate in a fun kids race.

Drop-off your child between 8:30-8:45 and pick up after the kids race (approximately 11 am) and pre-registration is required.

The cost is $55 per race day program ($45 for second child/sibling). If you are signing up for all four race days, the cost is $200 per first child and $180 for siblings for all four programs.

Swag

Each race in the series offers a different swag item, however our popular tri-blend shirts are available at each race if you'd prefer one of those instead. Please note that racers receive only one of these tri-blend shirts per series. There is also an option to not receive any swag by selecting "I Don't Want Anything" during registration.

Race 1 at Wakefield swag is a tri-blend t-shirt (our normal race shirts)
Race 2 at Laurel Hill swag is either a tri-blend t-shirt or a tech (polyester) shirt
Race 3 Pohick Bay swag is either a tri-blend t-shirt or running socks
Race 4 Lake Fairfax swag is either a tri-blend t-shirt or a custom car seat cover

Finisher Medals (Optional)

Race medals are an optional add-on for each race ($7.50 pre-order and $10 on-site). We do this because in our racer surveys we find that some racers do not want a finisher medal, so we make them an optional add-on to keep cost and waste down. Racers who complete all four races in the series will receive a special medal at no cost.
