Fresnan aims for 72-mile day>br /> Troy Kellenberger, a 21-year-old Fresnan who specializes in extreme speed hiking, is attempting to complete the High Sierra Trail across Sequoia National Park in less than 24 hours.

Kellenberger will leave Crescent Meadow at midnight Saturday and plans to be at Whitney Portal before midnight Sunday -- after summiting 14,505-foot Mount Whitney. Most parties take three to seven days to complete the 72-mile journey.

"I like the challenge and knowing so few people do things like this," said Kellenberger, who hopes to break the trail's unofficial speed record of 24 hours and 58 minutes.

Kellenberger owns the unofficial record for the Yosemite Triple Crown. In 2009, he hiked to the top of Half Dome, El Capitan and Glacier Point in 14 hours, 53 minutes. Last summer, he did Half Dome three times in 14:13.

Kellenberger will carry a SPOT satellite messenger with him, and you can track his progress at odwmountaineering.com.

News & notes

• Construction has begun on a new bridge at the Miami Creek Recreation area north of Oakhurst that will give OHV users better access between key trails and roads. The project is funded by two grants. One is from the state. The second was awarded by Yamaha to the Stewards of the Sierra National Forest.
