Paracyclist Mark Colbourne says his decision to retire was 'prompted by my age and by being honest with myself'.
I don’t feel I have the physical capabilities to continue for the next three years to Rio. I’ve really enjoyed my paracycling career, the standout highlight being winning gold at the Paralympic Games in London 2012.
I’m looking forward to being more involved with my Paralympic Ambassador role for the London Velodrome – I’m very proud of that. I’m going to be setting up my own cycling training camp company which will help other people to learn and develop their cycling skills from grass-roots up to club level. I’m also going to continue with my professional speaking.
