Portland Trail Blazers great and 1977 NBA Finals MVP Bill Walton will be back in the Rose City this weekend for a bike ride with fans ahead of the team’s 50th anniversary season.

The event, dubbed Bike with Bill and the Trail Blazers, is set to begin at 2 p.m. Sunday, with fans gathering at the Veterans Memorial Coliseum Commons. At 2:30 p.m., Walton and fans will set off for the bike ride to Terry Schrunk Plaza, where the Blazers’ championship parade ended 42 years ago. After the bike ride ends there about 3:15 p.m., the Blazers say they plan a special announcement at 3:30 p.m., followed by live music at 3:45 p.m. from Grateful Dead cover band Garcia Birthday Band.

During his playing days, Walton would often bike to Blazers games, and he also rode to the championship parade in June 1977.

This weekend’s bike ride will travel along part of the Sunday Parkways Green Loop that is open from 11 a.m. to 4 p.m. Sunday.

Fans who attend the Blazers’ bike ride can enter a sweepstakes to win one of five Blazers-decaled bikes. Fans also can enter a promotion via social media for the chance to win Walton’s bike — a Blazers-branded cruiser signed by Walton — and they need not attend the ride to enter that giveaway.
