I did a similar charity skate challenge last year with a goal of 50km with me finishing at 80km. This year my overtime goal is 150km if I get enough good weather to push myself beyond the 100km.
Millington's Magical Barn are a lovely vegan ran animal sanctuary that currently look after around 90 animals that were victims of neglect, abuse or were headed towards slaughter. At Millington's they wil be looked after for the lenght of their long natural life. They even look after a few disabled animals too.
Please donate if you believe in this cause, as well as motivating me to push myself further fitness wise!
