If you're new to Parkour, have been training a while and need a safer environment to practice in to train a move you're having trouble with, or just want to get inside out of the cold and still train, there are indoor Parkour jams that are held on a monthly basis. Currently they are held at these 2 locations:

Mt. Baker Gymnastics
1357 Pacific Dr
Burlington, WA 98233-3128
(360) 757-7565

Hart's Gymnastics
4520 B St NW Suite C
Auburn, WA 98001
(253) 520-1973

The next January session at Hart's Gymnastics is Saturday 1/19 from 5p to 8p. Details can be found in the calendar or Jam Planning. Keep an eye on the calendar for Gym Jams every month!
