The RAF's leading distance runner is hoping to create a world record next year as part of the service's centenary celebrations.
Senior Aircraftman Mike Kallenberg is hoping to help set the record for 100 athletes completing a 10,000 metre relay - along with 99 of his air force colleagues.
To beat the current record of 69 hours, six minutes and 52 seconds each athlete will have to complete their stage in an average of around 41 minutes.
He's got about 105 names so far but wants around 120-130 in case people drop out or get injured closer to the time.
Over the past couple of years SAC Kallenberg has shown he's a real talent in British distance running - on the track, in cross country and on the road.
He's running the Berlin marathon this weekend and already holds a world record in his own right.
A year ago he and his friend Carwyn Jones set a Guiness World Record at the Cardiff Half Marathon, for the fastest-ever run in fancy dress as Batman and Robin.
The current forces half marathon and 5000m champion heads to the Berlin marathon this weekend with selection for next year's Commonwealth Games high on his agenda.
And while it's early days at the moment he's already thinking about possible venues. All being well the attempt will happen next spring or early in the summer.
