Ultra marathon for greyhound rescue

I am running an ultramarathon (50km) in July to raise money in aid of Greyhound Rescue Wales and every donation will help. My previous longest run is 23 km so this is more than double. Greyhound rescue are a rescue and rehoming charity for greyhounds and lurchers in Wales. They work for a Wales without greyhound racing, where every greyhound and lurcher has a home and receives the best possible care.

Thank you for any donations to help this cause.
