RUN S.O.B RUN

RUN S.O.B RUN is held in Yorkville, Illinois, on March 13, 2027. The event lists a single format, the S.O.B. RUN 5k, a 5K (3.1 miles) starting at 9:00 AM.

Mid-March in northern Illinois is when winter mileage finally turns into race fitness, which makes a road 5K a useful checkpoint before the spring calendar fills up. Three miles run hard gives you a current time to work from: it sets the threshold and interval paces you will use for a 10K or half marathon later in the year. Four to six weeks of steady running with one faster session a week is enough to prepare, and an easy day beforehand does more good than a last hard workout. Dress for a cold start you will forget about after the first mile, and plan on even splits rather than a fast opener.
