Follow the Seagulls: 50 miles, 2 days, on foot For the first time our long distance charity trek comes to Brighton! The challenge is to take on 50 miles over 2 days, all in support of the 30 people who are diagnosed with a brain tumour every day here in the UK. For those 30 people, the road ahead looks scary and uncertain. By taking part in Follow the Seagulls, you'll aim to raise £500 to ensure that brainstrust can be here to help families feel less afraid, less alone and more in control.
