The responses vary but the most common are: 'Why', 'You're crazy', 'Don't be stupid', 'Oh for goodness sake (that was my mother) or rolled eyes (my wife) and laughter (work colleagues).
But after over a year of flirting with minimalist, natural and true barefoot running, I have agreed to take on the challenge.
And I'm a little scared to be honest.
I do believe the hype about barefoot running. It has helped me run faster than ever before - this year I took 7 minutes off of my previous year 10k time, recording a personal best of 41.08 at Bognor in May. And I have been able to run injury free which I couldn't do in trainers.
But I've never run 13 miles before, let alone a multi terrain course that includes chalk pit lane. Or as I call it now, the road to hell.
But after extolling the virtues of barefoot running to everyone that will listen and mainly those that don't want to, I feel I need to put my money where my mouth is, or perhaps my feet where others shoes will be.
And of course, running the event my colleagues at Children on the Edge organise in my home town seemed like the perfect opportunity.
So I'm training hard, building up the miles and all being well, on the morning of October 13th instead of pulling my trainers on, I'll be taking them off and lining up with the other athletes for the Chi Half.
Sportsmen and women are good at goals. So here's mine:
1. Complete the Chi half barefoot 2. Get round in 1hr 45 or less 3. Raise some funds for the work of Children on the Edge which frankly is much more important than whether I wear shoes or not.
Feel free to follow me on Strava (search for Ben Wilkes) or say hi if you see me running around Chichester, I'm not hard to miss!
And if you would like to help me achieve goal #3, text FEET74 £3 to 70070 to donate £3 or visit JustGiving page here. Thank you.
