Load the wheelbarrow to your weight tier, take both handles behind you, and walk backwards pulling it 200 metres as fast as you can. You may set it down to regrip; the clock keeps running.

Declare your weight tier before starting; the distance is always 200m. You face away from the barrow and pull for the whole distance — turning to push voids the attempt. The load stays in the barrow; spilling it means reloading before you carry on. Fastest time at your tier wins; a higher tier always outranks a lower one.
