About
The Secret Half is the perfect race for getting that PB! It's got the same elevation gain as Crewe parkrun. The Secret 20 miler, with only 280ft of climb over 20 miles, is ideally placed for a spring marathon - only 5 weeks before Manchester and 6 weeks before London, perfect to see how your marathon prep is going!
