X-S-N-R-G = excess energy!

XSNRG is a running club that provides runners of all levels weekly coached interval training to develop strength, stamina, and speed, in a supportive and social environment. From beginners to accomplished competitive runners, no one is too slow or too fast to run with XSNRG – all you need is the desire to train and improve your running!

Structured workouts will help you improve, but they are not always easy to do on your own. Our Tuesday night workouts, led by coaches, make it easy, give you company, and help keep you motivated with your running.

The club meets in the Leaside area every Tuesday night at 6:30 p.m. and runs to a different workout location each week, focusing either on speed intervals or hill training. A typical workout includes a warm-up, cool-down, coaching tips on technique and the workout, and is usually finished by 8:00 p.m.

Meeting Locations:

  • May through September: Sunnybrook Park in the Sports Pavilion parking lot on the upper fields
  • October through April: Leaside High School

Join us for our Tuesday Night Workouts … you’ll have fun and improve your running – all because of XSNRG’s workouts!
