AN “INCREDIBLE effort” was how Esther Hyman described more than 20 people cycling from Oxford to London in memory of her sister.

Today marks exactly 10 years since Miriam Hyman and 51 others were killed in the London 7/7 bombings.

Esther, who lives in Cowley Road, organised Sunday’s memorial cycle from her home in Oxford to London, where she and her sister grew up together.

The 46-year-old took to social media to thank everyone who was involved and said it was an “incredible effort”. Money raised is still being counted.

Speaking to the Oxford Mail she said: “Mim’s energy came through and it was an uplifting day. There was a real feeling of mutual support.”

Among the other cyclists was 60-year-old Tim Coulson – the “Angel of Edgware Road” – who comforted some of the dying on 7/7.

The cyclists were raising money for the Miriam Hyman Memorial Trust which Esther Hyman founded to create something positive from the tragedy.

Last week the trust launched its latest initiative – a website to teach schoolchildren about the terrorist attacks.

The educational resource contains plans for geography, citizenship, art and dance lessons all based around the 7/7 bombings.

About 770 people were injured as three bombs went off just before 9am on underground trains near Liverpool Street, Edgware Road and King’s Cross stations.

The final explosion about an hour later was on a double-decker bus in Tavistock Square. On board was freelance picture researcher Miriam Hyman, 32.

The free online educational resource for 11- to 14-year-olds was developed in partnership with the UCL Institute of Education and the sisters’ old school in Barnet.

Miss Hyman, the charity’s director, said she wanted to prepare young people for dealing with trauma in their lives.

She said: “All our lesson plans take Miriam’s story as a starting point – history, citizenship and personal, social and health education are based on the events of 7/7.

“We want to give young people the tools to deal with adversity to improve their own lives and their society.”

Today Miss Hyman will be joining official memorial ceremonies at St Paul’s Cathedral and Hyde Park in London, before a more private ceremony with her family at the park in North London where she and her sister used to play.
