At 10am, the first of over 80 supporters will set off from Wolverton to walk the 18 miles up the Grand Union Canal to Franklin's Gardens. This annual event, known as Saints With Heart, has raised around £130,000 for the British Heart Foundation over the past decade, and the organisers are hoping for another five-figure sum this year, too.
One of the organisers is Simon Robinson, whose brother Gareth is also doing his bit in the black, green and gold to raise cash for the BHF. That's because on Sunday Gareth will be donning the famous Bernie suit to take part in the London Marathon, the last of six half-marathons and eight marathons that Gareth has completed over the past year. If you're heading to London on Sunday keep a look out and give him a special cheer!
Meanwhile the bucket shake on Saturday will be to help support Brian Facer (head of commercial operations), Paul Shields (team manager) and Ross Stewart (EPDG manager) in raising cash for Marie Curie Cancer Care.
The trio's efforts will culminate in their assault on The Wall, an ultra marathon in mid-June which follows the route of Hadrian's Wall between Carlisle and Newcastle. They are aiming to complete the 69 miles in under 24 hours and are well in training - you can follow their progress at either www.twitter.com/paulvsthewall or www.twitter.com/brianfacer
