Lexington's Urban Mountain Challenge

Dr. Jonathan Feddock of Lexington is a true stair master. The 30-year-old radiation oncologist climbed 29 stories of the Lexington Financial Center, the city's tallest building — 638 steps — in 2 minutes, 46 seconds to take first in the overall male division of Saturday's inaugural Urban Mountain Challenge, organizers said. And get this: He did it after breaking his right foot during an October run.
