Leesburg Mayor Kristen C. Umstattd will be the official starter for the 17th annual race to raise money for charities and the YMCA's building fund at 8:15 a.m. Sunday. There will be a course change this year because the Virginia Department of Transportation no longer permits races on Dry Mill Road and the town of Leesburg wants to minimize traffic disruptions. The race will still begin and end at Market Station on Harrison Street and turn right onto Catoctin Circle, but the course will then turn right into the Virginia Village Shopping Center, run through the parking lot to King Street, turn right on King and then make a quick left onto the W&OD trail for an out-and-back run. Because the trail is only eight feet wide, the race will start in waves, but at some points there will be runners moving in both directions on the trail. Registration starts at 7 a.m. A Kids Fun Run will begin after the 10 kilometer race. Prizes, refreshments. 10K, $25; 20K, $35. 301-871-0400 or www.runwashington.com.


Heritage High School will host a musical theater cabaret to raise money for the Leukemia & Lymphoma Society. The production by the DC Metro Players will begin at 8 p.m. Saturday, 520 Evergreen Mill Rd. SE, Leesburg. $15; cash or checks only. 703-246-0270 or www.broadwaylightsthenight.com.


The second annual festival features music, hayrides, a cupcake walk, field games for children, face-painting, a milk-bottle toss and a bale maze. Peaches, of course, and other food will be sold. 10 a.m.-5 p.m. Saturday and Sunday, Valley View Farm, 1562 Leeds Manor Rd., Delaplane. Sponsored by Victory Thru Jesus Ministry to benefit the Praise and Worship Center Project. $15 per vehicle. 540-592-3730 or www.valleyviewfarmva.com.
