Plan your London Marathon splits

The London Marathon course is mostly flat route from greenwich to the mall, passing cutty sark, tower bridge, the embankment, and buckingham palace. A pace plan for this route should account for where the course asks for steadier effort, where climbs may slow target pace, and where descents or flatter sections may allow time back.

Enter your goal finish time, select kilometers or miles, and calculate a split plan that keeps the total time aligned with your target.
