WASHINGTON (WUSA9) -- WUSA 9 reporter Larry Miller is set to embark on the longest run of his ultra-marathon career.

He, along with nearly 200 other runners, will take part in the Massanutten Mountain Trails 100 (MMT) mile run in Fort Valley, Virginia Saturday.

Yes, 100 miles! The course will take Larry over several mountains with climbs that total over 18,000 feet.

He's been training for several months now and recently completed the Bull Run Run 50 mile race in Clinton, Virginia in April.

The MMT 100 begins at 4 a.m. Saturday. You can track his progress by visiting this site: http://www.vhtrc.org/mmtlive/
