Today’s #nyrrvirtualtrainer #RuntheHolidays challenge: Wear an #unglyholidaysweater proudly on the run. Running through New Year’s Day in 2015, the coaching staff from NYRR Training will be encouraging our community to keep active through the winter holidays with a series of daily social media challenges. Tag your running buddies to take part and post your response to the challenge(s) using #runtheholidays. #holidays #christmas #uglysweater
