A former Grange pupil is cycling from Portugal to Brighton for charity.
Tim Lambrechts is hoping to complete the challenge in three weeks.
It is made all the harder by the fact he has to use a specially-designed bike after suffering a stroke following an operation to repair a hole in his heart at a young age.
Mr Lambrechts was also diagnosed with cancer in 2009, something treatment has beaten.
He is hoping to raise £1,000 for Sussex Cancer Fund. Sponsor him at www.justgiving.com/tim-lambrechts
