The annual Seattle Bicycle Expo runs today and Sunday. If you haven't been to a bike-related expo in years, head south. You can donate your old bike tubes to Green Guru in exchange for a change pouch made from inner tubes and created on a bicycle-powered sewing machine.
Those 10 or older can try a mountain bike challenge course (there's one for the adults too).
Bike-racing pioneer and two-time Olympian Ron Hayman, captain of the internationally famous Team 7-Eleven, will join the author of "Team 7-Eleven" and former editor of Bicycling Magazine Geoff Drake to talk about the team's origins, which started with a pair of Olympic speed skaters.
They are scheduled for 12:20 p.m. today and 1 p.m. Sunday.
Learn everything you need to know about the Seattle to Portland Bicycle Classic or watch the BMX stunt team. Go to a class about bike maintenance, learn about pedaling toward a healthier planet, how to ride faster or catch a cooking demonstration.
Go behind the scenes of professional cycling; listen to Kevin Sayles, master frame builder; attend a workshop on reflective vest and patch-making; or browse 250 booths.
The Expo runs 9 a.m. to 6 p.m. today and 10 a.m. to 4 p.m. Sunday at Smith Cove Cruise Terminal, 2001 W. Garfield St., Seattle. Tickets at the door (cash only) are $10 for one day, $12 for two days. Ages 15 and younger are admitted free.
The Seattle Bicycle Expo is sponsored by the Cascade Bicycle Club. For more information about the the Expo and other CBC events, go to www.cascade.org.

On the boardwalk: The seven-mile Grand Ridge Park trail, a Washington Trails Association project, was recently completed with a 600-foot boardwalk.
The trails association started working on the King County multiuse trail system in 2000. The Grand Ridge Park trail will be shared by hikers, mountain bikers and horseback riders.
The 1,200-acre park includes groves of Western red cedar, some more than 5 feet in diameter.
The trailhead is 18 miles east of Seattle on I-90. Take exit 20, turn left, go underneath the interstate and park in the gravel lot to the west. Hike or bike west about a half-mile on the Issaquah-Highland Point trail to the backcountry trailhead.
