I'm joining a group trekking to the summit of Ben Nevis - the UK's highest peak - for two reasons.

1. Because it's there.

2. To raise funds for Muscular Dystrophy UK.

In particular, the charity helps people with Duchenne Muscular Dystrophy.

This is a devastating muscle-wasting condition and our friends’ brilliant little boy (Kitto) was recently diagnosed with it.

This is for him - and all the other little boys and families affected by DMD.
