I realise you all want video footage with GPS watches surgically attached to Rob's leg and at least 5 different TV companies following his every step but this wasn't possible to arrange. I'm sure even if this happened many of you would still not believe it.
No, just one watch with data uploaded after each stretch - OK, I will give you two watches so one is always charging.
I was quite happy to be on the ground if the charity was willing to pay my flights and accommodation
I like the irony of your "short update"
