I am running the Stirling Marathon on 21st May to raise money for the MS Society.
My dad has this condition but he hasn't let it beat him in spite of some quite stark effects on his balance and the coordination and control of his limbs over the years.
He still regularly cycles 50 miles at a time on his road bike averaging 20mph having made some personal modifications to his bike which I think is properly impressive given the hurdles he's overcome.
He will be cycling alongside me on my longer training runs for company and to provide some choice advice like "don't be weak" if needed.
Any donations in aid of the charity which funds research into this condition would really be appreciated.
