The 26th annual Octoginta bicycle ride is set for Sunday.
If the weather forecast holds -- high temperatures are supposed to be in the 60s with no rain -- there may be as many as 700 or 800 riders, said Jim Turner, president of the Lawrence Bike Club, which sponsors the annual ride.
The 80-mile ride will begin at the South Park gazebo about 8:30 a.m. The route will be south along Massachusetts, west on 19th, south on Louisiana, west on 31st, south on Osdahl, south on Iowa/U.S. Highway 59, and west on County Road 458 to Lone Star Lake.
"We want motorists to know where the ride is going to be so that they can plan on taking a different route if they want," Turner said.
"When you have 700 or 800 bicyclists, it can really clog up the roads, but if motorists could remember, that's 800 less cars on the streets."
Turner said as of Thursday night, 260 cyclists already had signed up for this year's main ride on Sunday.
"It's the most people we've ever had sign up this early," he said. "Typically, we have about a third sign up of what we usually get -- that's why I'm anticipating we could have as many as 700 or 800."
The ride's name was coined several years ago by a Kansas University linguistics professor, Turner said.
It comes from the terms "octo" for 80, and "ginta" for ride or route, he said.
"It's the windup of the season and meant to be the last ride of the season."
Several events also will be held Saturday, including two 30-mile rides, bicycle maintenance seminars, a racing clinic and a swap meet. Fees will be charged for some activities.
A registration fee also will be charged for Sunday's ride. The fee includes lunch, and snack and fruit stops along the route.
People may register from 8 a.m. to 7 p.m. Saturday at Centennial School and at 7 a.m. Sunday at South Park.
Participants are reminded that daylight-saving time ends on Sunday.
On Saturday, the Bicycle Club also will present a plaque to Lawrence Mayor Bob Moody at 7:15 p.m. at Centennial school, for his support of bicycle programs.
