Peterborough

Peterborough sits on the Nene in dead-flat Fenland where time trials dominate: the Fenland Clarion CC 25 and VTTA 25 are bread-and-butter circuits on pancake roads around the city and into Cambridgeshire, with zero elevation to chase down. Runners treat the Peterborough 5K Grand Prix as the local track series, though the terrain offers nothing but flat; the real running draw is distance on the Nene towpath or loop routes through the fens, where you're fighting wind rather than hills.
