This Thursday, 14th November, BBC One's The One Show is broadcasting live from outside Balliol College in Oxford at 7pm, as part of a Children in Need special. The programme will be welcoming its team of rickshaw riders, five teenagers who are cycling 700 miles across the country, non-stop over eight days.To celebrate their achievement the show has collected a group of Oxford academics including Jon Chapman, Professor of Mathematics and its Applications, to answer some challenging questions (well, challenging in the loosest sense of the word) about travelling by rickshaw and the meaning of life.
