A 13 year old boy has taken the ultimate London Tube challenge – visiting every one of the 270 stations in a day to raise money for charity Bloodwise, after his 17 year old brother died of lymphoma in March.

Alasdair Clift started his marathon Tube ride in memory of his brother Adam at Chesham at 5.15 am on Monday August 1 and finished it at Heathrow Terminal 5 after midnight. Due to the kindness of sponsors the money raised boosted his original target of £100 to more than £11,000.
