A photographer cycled more than 100 miles on an exercise bike to raise money for Great Ormond Street Hospital after his son received a life changing operation there.

Ian Burt, a photographer at the Eastern Daily Press, took part in the challenge on Tuesday with reporter David Blackmore.

The pair were aiming to cycle 106 miles each on the bikes – the equivalent of a return trip from the London-based hospital to King’s Lynn.

Ian’s youngest son Calum had an operation on his skull at Great Ormond Street two years ago.  He and his wife Rebecca were so delighted by the treatment he received that he is now aiming to raise over £1,000.

Said Ian:  “Everyone at the hospital was fantastic to all of us and really helped us pull through.

“They have to deal with a lot and to be honest I am not sure how they manage to deal with it but they were so great to us. It’s an incredible place but they rely on £50m of charity donations each year so that is why we decided to do our bit to help.

“The last time we went to Great Ormond Street, there was a couple there with a baby girl. You could see they were really upset and I just knew they had just been told the same news we were told two years ago.”

For David this will be the second long-distance exercise bike ride he has taken part in. The 25-year-old cycled the equivalent distance of King’s Lynn to Calais – 139 miles as the crow flies – last April to raise money for the Bobby Moore Fund.
