KAPALUA, Maui >> Lance Armstrong will compete in the XTERRA Worlds off-road triathlon.

“XTERRA World Champs next wknd. I’m in! Looking fwd to racing,” the seven-time Tour de France winner tweeted Sunday, a week before the swimming, cycling and running competition in Maui.

Last month in Colorado, Armstrong was fifth in the XTERRA USA Championship, finishing the 1,500-meter swim, 17.7-mile mountain bike ride and 6.1-mile trail run in 2 hours, 29 minutes, 25 seconds.

The Hawaii event features a 1,500-meter swim, 18.3-mile mountain bike ride that climbs more than 4,000 feet up and down the lower slopes of the West Maui Mountains, and a 6.1-mile trail run that traverses forest trails and beach sand.
