Iva Barr, 86, ran the marathon for Whizz-Kidz for the second consecutive year. Iva, from Bedford, is the UK's oldest female marathon runner, and only began distance-running in her 50s. She says: 'I have seen first hand how the money raised helps Whizz-Kidz transform young disabled children's lives. The kids are so inspiring!' Photograph: RobDyson/GuardianWitness
