The Boundary Run Half | Marathon takes participants around the boundaries of Cambridge. The course traverses roads, footpaths and trails, and incorporates some beautiful and not-often-seen areas of the city. It's a laid back event with a friendly and pressure-free atmosphere.
Both courses are about 30% off-road, and there are several reasonably sized hills on the course - significant enough to surprise those who are used to the flat terrain of Cambridge. This is a challenging but fun and rewarding course.
