10-year-old Jonjo leads charity walk along South Bank & Bankside

10-year-old Jonjo Heuerman started his campaign to raise money for Cancer Research UK's Bobby Moore Fund following the early death of his grandmother in February 2009. Both Bobby Moore and Jonjo's grandmother Lyn were victims of bowel cancer.

His first walk "for Nanny and Bobby" last year involved just six people including his sister Megan on the first day but interest grew and he raised over £40,000 in donations.

This year's three-day walk covering 23 miles started on Thursday in front of Wembley's Bobby Moore statue.

The second leg on Friday, taking place on the anniversary of Bobby Moore's death, began at 8am from Marble Arch. The day was due to end with his party arriving at Canary Wharf in the late afternoon.

Jonjo led his fellow walkers, who included his mother Donna and father Garry, over Westminster Bridge just ahead of the scheduled time of 10.45am.

This nine mile route was the longest so far. Asked about the distance, whilst taking a break at The Real Greek restaurant on Bankside, Jonjo said: "I know it's going to make my legs ache again."

The restaurant, which has supported the fundraising walk, provided refreshments.

The final day is a six mile walk to Upton Park where football fan Jonjo is expected to receive a special welcome at the West Ham ground before the kick-off with Crystal Palace.
