My challenge will run from April 3^rd 2022 when I take part in the Guernsey Marathon, until the end of April 2024, taking in London Marathon (April 21 2024) as my last event. That is the year when our wonderful RNLI will be celebrating its bi- centenary!  I will aim to run/walk 200 miles per month during that period - which I think will be tough for me.
