Many of you know I ran the London Marathon in 2016 in support of Alzheimer's Research UK. It was a fantastic day and an unforgettable experience. 

My father Robert had Alzheimer's disease and sadly passed away the following year. I want to raise more money for a charity that is committed to research into the condition and finding treatments to help patients.

This year, I've upped the ante and entered into my first Ultramarathon. This is a 106km (66 miles) run around the perimeter of the Isle of Wight. It's a very long way and it isn't exactly flat, with over 2100 meters of climbing. The time limit is 16 hours. I'd better get a move on!

Training has been going well. I've run up to 30 miles but that's still less than half the total distance of the main event. Eek!

I'll be carrying my water and food supplies for the trip, along with the mandatory safety equipment in my rucksack such as headtorch, whistle and waterproofs.

This will be a challenge and considerably outside of my comfort zone. There will be pain along the way but glory at the end!

Thank you for anything you can give to support Alzheimer's Research UK.
