ROCHESTER, N.Y. — Runners bundled up Saturday morning for Fleet Feet’s “Winter Warrior” half marathon.

The run spanned 13.1 miles, starting at Monroe Community College. Participants also had the option to run a quarter marathon, or to have a four-person team in which each member runs around 3.1 miles.

Athletes took off from the starting line at 10 a.m.

For some runners, this marks the start of their “Four Season Challenge.” The challenge tasks runners with completing either four half marathons or four 5K races through winter, spring, summer, and fall.

Participants, packed their hats and gloves. It was s a balmy 29 degrees outside and only expected to hit a high of 34 degrees in the afternoon.
