Thanks for all the concerned tweets yesterday after I revealed I was being trained by a BMX stunt rider.

It won’t surprise you to know that this was at the request of Leukaemia and Lymphoma Research, for reasons which will become clear in due course.

But today, I want to highlight the efforts for the charity of Jez Davison and Gareth Crockett who will set out this Sunday on the inaugural Beldon Challenge: travelling from Belfast to London on bike and foot in just eight days, completing four marathons along the way, culminating in the London Marathon itself.

In total they will cycle over 450 miles and run more than 100 miles in eight days,with marathons in Belfast, Dublin, Bristol and London. The goal is to raise more than £10,000 in memory of their close friend, John Erwin, who lost his life to leukaemia aged 26 last year. His name was John Erwin. He was born and grew up in Moira, Belfast — where the journey begins – and studied and worked in London, where it will end.

If you would like to donate please go to –

And for any media who may want to publicise their efforts, here is the schedule.

Sunday 10 April – 26.2m run, Belfast

Monday 11 April – ca. 100m cycle, Belfast to Dublin

Wednesday 13 April – ca. 250m cycle, Holyhead to Bristol Day 1
