The appearance – co-ordinated by British Cycling’s Gary Coltman – will feature the British Cycling Talent Team Stage 2 test and there will be three youngsters taking part together with Rob Hayles and one of the Blue Peter presenters.
Hayles and either Matt or Simon will go ‘head to head’ on static bikes with live readouts from their SRM cranks.
The live programme airs at 6pm on CBBC and then it goes out again on BBC1 on Wednesday at 5pm.
