Narrowleaf Lake Run

The Narrowleaf Lake Run is an annual fall running event at Boyd Lake State Park in Loveland, Colorado. The event offers several distance options, a pumpkin mile and kids runs, and takes place along paved park walkways with a short off-road section on the south loop.

Distances offered:

  • 1 Mile Pumpkin Run carry a pumpkin during this one mile course
  • Heavy 5K (4 mile) course
  • Heavy 10K (7 mile) course
  • Heavy 15K (10 mile) course
  • Kids Fun Run, 1/2 mile and 1 mile options

The course is largely flat with little elevation gain and provides lake and wildlife views. There is no vehicle traffic on the course. Aid stations provide cups of water, electrolyte drink, snacks and gel-packs; cups are 100% biodegradable. All aid stations include dog water bowls. Specific aid station passes per course are noted on the course maps: the 4 mile route passes the south #1 aid station three times; the 7 mile route passes south #1 three times and #2 once; the 10 mile route passes south #1 three times, #2 twice and #3 twice.

The event is USATF sanctioned and described as a 100% plant based event, with vegan and vegetarian friendly options prioritized among vendors. Parking is available in nearby lots within a short walk of the start and finish, and parking passes are required. This is the eighth annual running of the Narrowleaf Lake Run.
