The report isn't quite accurate - although the chap is to be admired nevertheless.
In 2017 an 89 year old man, Norman Franklin, rode the E2E - but he was on an electric bike so perhaps not quite in the spirit of the cycle ride?
I've just re-vamped the www.cycle-endtoend.org.uk
website - the one section that is yet to be updated is the "Records" .... as there is no official event or route/rules for the event it is difficult to publish the accurate or definitive facts with any certainty.
As the site owner I get loads of claims for youngest/oldest rider but they can seldom be substantiated. There are a couple of record-recording associations that do scrutinise record attempts and those records are perhaps the ones to publish?
I'd be very interested to receive feedback and thoughts on the records etc in order to improve the website content
