Grace House is a fantastic charity. Based in Sunderland, it provides care for young people and children with a vast array of complex and life-limiting conditions and disabilities, and does a lot of incredibly important work for families across the north east of England.

Grace House is our college charity. As a result, when exams finish this year, we've decided not to merrily sit around and soak up the sun that we're already crossing our fingers for, but instead to merrily walk up and down the three highest peaks in Yorkshire, in a single day.

We'll have checkpoints along the way and water refill spots, but it's going to be pretty tough; the full length of our route totals almost 29 miles, and - as you might expect - a significant amount of that will be up very steep slopes. There are a big bunch of us taking part in the walk, and we'll be doing it in five groups overall.
