Monster Run Fest
One day, 3 events - half marathon, marathon and ultra, at Monster Run Fest! Starting outside Ely Cathedral, this flat, well-marked ultra run passes through the city and onto the banks of the River Great Ouse. Through desolate Fens, it takes the path along the River Cam to the outskirts of Cambridge. It then follows the same route back to the 'Ship of the Fens'. Ideal for those looking for something to fill the gap after a season of Ironman racing.
