This is from the BBTC website:
I-5 Colonnade is the first ever urban mountain bike skills park. It's part of a City of Seattle park, but was funded and constructed by the BBTC (Backcountry Bicycle Trails Club).
The Novice Area (Phase 1) is complete and offers a 1/2-mile tight'n'twisty Cross Country loop trail with several intermediate to advanced options.
It's a great place to work on key skills be sessioning:
- Ladder bridges, log rides and skinnies
- Tight switchbacks
- Steep rock chutes and technical rock rolls
- Teeter totters
- Rock step-ups
- A long ladder bridge roller coaster ride (be careful to keep your speed waaaay down... she bucks!)
Phase 2 is under construction and scheduled to be completed by Oct'08. Phase 2 will focus on more flowy advanced trails and offer features like jumps, berms, wall rides, progressive drops, rock chutes, skinnies, pump track, trials area, etc. and a couple of sessionable practice areas.
