Colne Valley postman Rob James will swap his normal delivery round for an incredible ultra marathon challenge for charity this weekend.

Slaithwaite postal worker Rob is one of many intrepid racers, who will put themselves through the paces in Sunday’s daunting run around the Colne Valley, and he is doing it for Cancer Research UK.

All are taking part in the White Rose 60 and 30 mile Ultra races.

Pitting himself against the unforgiving Pennines weather and long, tough climbs, Rob, 27, hopes to honour his granddad Trevor through his 60 mile attempt and continue Trevor’s legacy that he started when he swam the English Channel for charity.

Rob, who lives in Springfield Avenue, said: “Since my granddad did the race when I was a kid I’ve always been thinking of what challenging event I could do and this race is it.”

He decided to pick Cancer Research UK in memory of his granddad, who died of melanoma, and several other family members including his dad and auntie who survived the disease.

The runners will start at Marsden Cricket club at 8am and will take a gruelling double loop route up onto the moor then pass through Meltham, Linthwaite, Golcar, Scapegoat Hill and Slaithwaite.

It is nothing like the gutsy runner has ever done before, despite being a regular face on the area’s running race scene.

Rob said: “I do a lot of running and have done marathons before but never something this long.

“Normally I’d train a lot in the run up to an event but because of this race’s length I’ve just been taking it very easy for the past week in preparation.

“It’s going to be a very hard, long slog and don’t think that there’s any chance of me finishing it until at least 6pm.

“I’m feeling a bit nervous and hope that the weather is on my side but hopefully it should go well and I’m doing it for a good cause.”
