Heads up, weekend warriors, people affected by cancer and anyone who wants to hop on a bike and go for a leisurely ride in what’s shaping up to be spectacular weather.

The 2013 Team Livestrong Challenge unfolds at 7:30 a.m. Sunday, departing from Auditorium Shores and heading south on routes of 20, 45, 65 and 100 miles.

The ride has changed over the years. What started as a race between Livestrong Foundation founder Lance Armstrong and his cycling buddies for a bouquet of roses grew into a huge fund-raising event that drew thousands of participants. It was one of the biggest events of the year for the Austin cycling community, and it raised money for a good cause.

Armstrong is gone from the foundation now, after admitting in January that he doped while racing the Tour de France. But the Livestrong Challenge still benefits the foundation, whose mission is to improve the lives of people living with cancer. That remains a good cause and the ride is well organized and fun.

Registration is $70 at www.TeamLivestrong.org, or you can sign up in person at the Livestrong Village at the Palmer Events Center, 900 Barton Springs Road. There’s no longer a fund-raising minimum to participate.

Rider check-in is from 3-7 p.m. Friday, 9 a.m. to 3 p.m. Saturday and 6:15 to 7 a.m. Sunday at the Livestrong Challenge Village. The ride starts at 7:30 a.m. Sunday on Riverside Drive near Auditorium Shores, and heads east to South First Street, then south. The beer tent opens at 10 a.m.
