to launch the Register And Be A Lifesaver project in the city.
The pilot project trains volunteers to give talks to students in sixth forms and colleges about blood, bone marrow and organ donation.
Adrian, 27, died last August from leukaemia, but had spent his final months fronting campaigns for 17 and 18-year-olds to be educated about donation.
Mrs Sudbury gave a talk to students at Cotham School along with David Gates, of Bedminster, Bristol, whose 15-year-old daughter Yvette needs a bone marrow transplant for aplastic anaemia.
Mrs Sudbury said: “The feedback from talks so far is that they’ve been very well received.
“The talk in Bristol went well and David spoke very powerfully and movingly.
“It was quite a day, tiring and emotionally draining but good.
“The fact that we have done this launch in Bristol just shows how far we have come.
“The fantastic volunteers that have come forward have proven to be powerful and engaging speakers.
“It is turning into a real success and I think our lad would be proud.”
Mrs Sudbury said: “If it’s a positive evaluation and the pilot continues, schools will be happy to be contacted again.
“Adrian would have been really chuffed, but he always knew it would succeed.”
