Lums Pond Triathlon

The event is staged out of Lums Pond State Park in Bear, Delaware and offers Olympic and Sprint triathlon and aquabike options. Distances include:

  • Olympic: 1.5K swim, 23 mile bike, 10K run
  • Sprint: 750 m swim, 10 mile bike, 5K run
  • Aquabike: swim and bike only for each distance

The swim takes place in a 200 acre pond averaging about 10 feet deep. Both Sprint and Olympic swims use a rectangular course with orange sighting buoys about every 75 meters and yellow triangles marking turns. A preliminary water temperature is posted before the event; race-day temperatures are typically in the mid 70s.

The bike routes are flat with all right-hand turns. Olympic athletes complete three 6.7 mile loops, while Sprint athletes complete one loop to reach roughly 10 miles. Pavement quality is noted as good.

The run follows heavily forested single-track and wide gravel paths around the lake. Aid stations appear about every mile and provide ice water and Gatorade. Spectating is possible at the wide-open swim start and finish areas. Post-race provisions include a tech shirt, socks, finisher medal and food and music.

The race is USA Triathlon sanctioned; nonmembers must purchase a required 1-day license. Packet pickup has two options at the race site; photo ID is required to collect race materials. Visit the organization's website for the most recent information.
