Mr Dipple's 50 mile Ultra Adventure 2025

Having completed 1 x 50 mile ultra marathon before, I wondered whether I might be able to complete 4 x 50 mile ultras in one calendar year. Known as the Centurion 50 mile Grand Slam this was likely to be the biggest personal physical challenge I've ever attempted, partly due to the testing cut off times at each checkpoint en route.

South Downs Way 50
North Downs Way 50
Chiltern Wonderland 50
Wendover Woods 50

Having seen the effects of Alzheimer's and Dementia on loved family members and friends I wanted to to raise a little money for this important charity too.

Update: I did it! Very relieved. They were all tough but this last one especially, with 10,000 ft / 3000 metres of ascent.

Only 39 of us completed the Grand Slam this year:
