Prolific marathoner, international shipbroker and Arlington resident Michael Wardian is trying out for the 2012 London Olympics.

Wardian, who ran in 26 races of 26.2 miles or longer in 2011, will compete in the Olympic Trials Marathon in Houston on Saturday. The 37-year-old told The Daily that starting marathon running in his 20s, rather than earlier in life, is helping his endurance now.

“I’m not burned out,” Wardian told the tablet publication. “Many top guys start running when they’re 8 or 9 and have been competing at a high level for a long time. A lot of people in their late 30s think they’re done with sports. I’m still setting (personal records).”
