Seattle celebrates two big annual traditions this weekend for those ready to rock ‘n’ run and bike in the buff. Metro buses The Rock ‘N’ Roll Marathon and Fremont Solstice Parade both will affect transit service, so riders should plan ahead and prepare for delays due to street closures and crowds.

Fremont Solstice Parade/Saturday

The Fremont Solstice Parade  starts Saturday at 1 p.m. from Northwest 39th Street and Fremont_solstice_avatarLeary Way Northwest and travels east along North 36th Street on its way to Gas Works Park.

Metro will operate a special shuttle from downtown to the south end of the Fremont Bridge. The shuttle service will operate every 15 minutes, from  10 a.m. to 7 p.m., starting from Sixth Avenue and Blanchard Street. Regular fares, transit passes and paper transfers will be accepted. (Try not to get body paint or glitter on the seats, please!)

Several bus routes that normally serve the Fremont area will be rerouted during Saturday’s parade, including routes 31, 32, 40 and 62. Sign up for transit alerts or check Metro online for service alerts.

Rock ‘N’ Roll Marathon/Sunday

On Sunday, runners will be out bright and early for the Alaska Airlines Rock ‘N’ Roll Marathon and half-marathon. The full race starts this year from Husky Stadium and makes its way through the Arboretum, down along Seward Park, up through the Rainier Valley and over to State Route 99 before looping back to CenturyLink Field.

For transit service during the race, the following routes will be affected by street closures: 2, 5, 7, 8, 14, 26, 27, 28, 43, 44, 45, 48, 50, 65, 106, 120, 125, 271, RapidRide C, D and E Lines, ST 522, ST 545 and ST 554. The Route 7 reroute will temporarily end at at Rainier Avenue South and South McClellan Street.

While runners are in the Rainier Valley, between 5:30 a.m. and 12:30 p.m., regular Route 7 service will operate between downtown Seattle and the Mount Baker Transit Center, and a free shuttle bus will provide service every 20 minutes between the Mount Baker Transit Center and South Henderson Street.
