Souderton hosts the end of the annual Bucks County Classic, a professional bicycle race.
The town was originally named Welshtown, because it was settled by the Welsh. Souderton is prefigured in a map of 1847 as Souder’s Lumberyard, and the new name was certainly in place by the railroad era in the second half of the 19th century.
Souderton is located at (40.310215, -75.321682).
According to the United States Census Bureau, the borough has a total area of 1.1 square miles (2.9 km²), of which, 1.1 square miles (2.9 km²) of it is land and none of the area is covered with water. The terrain is mildly rolling hills, with some steeper hills in the downtown area, and flat terrain throughout.
Souderton is home to Montgomery Theater, one of only three professional theaters in Montgomery County. Sitting in the historic firehouse on Main Street (Rte 113), the Theater produces five subscription-series shows each year, and offers education programs for students ages 8–18. Montgomery Theater draws people to Souderton from around the five-county area. Souderton also hosts an annual Art Jam every September, bringing artists and artisans to the borough park, and offering craft beer and wine tastings. This event is hosted by Souderton-Telford Main Streets, the non-profit organization that supports revitalization in Souderton.
Souderton was host to the Univest Grand Prix, a one-day road bicycle racing event that is part of the USA Cycling Professional Tour. It took place in early September and publicized its association with Floyd Landis. This event was part of a weekend of longer bike races in surrounding towns. Participants were from varying areas in the United States, and foreign countries, mainly European. Italian, French and Flemish teams often returned to the race annually. Although the race went professional, there were amateur races earlier in the morning for kids and adults. In 2012 the race was officially discontinued in the Souderton Borough.
