River City Micro Marathon
Race Day Weather
Cold start — layer up, warming through the race
Runners will start in chilly 39°F conditions — dress in layers for the corral and plan to shed early. Temperatures rising to 51°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing.

Race Info
The River City Micro Marathon is held each January at Point Mallard Park in Decatur, Alabama, near the Tennessee River. The marathon is run as six laps of a USATF-certified 7.03 km loop through the park, with aid stations about 2 and 4 miles into each lap and a 6-hour time limit. A 10K, a 5K and a marathon relay start the same morning, and net proceeds go to the Decatur High School track and field team.
