Hello and Confused

[The muleteer]

Hi.

I am currently researching the tube challenge for a project. I have registered on the Guinness Record site and am confused by what seem to be contradictory rules.

It says an independent person must take a master stop watch but further down it says 2 members of athletics clubs must record two times.

Also it says time must start when the door closes on the first train but further down it says time must start with a loud bang...

Thanks, and hello

Hello and welcome, don't be confused GWR like to put a curve ball in there...

As long you have the 2 athletes running and make that load noise at the start you will have met the required criteria
