Charity WildHearts aims to get Scottish children fitter and healthier and expects to have hundreds of children and families taking part in the event on 25 April.
The Edinburgh Solicitors Property Centre is to help sign up families for the event at its George Street showroom on Saturday.
WildHearts mascot Marco the Monkey will be in the showroom to encourage people to take part.
ESPC marketing manager Neil Harrison said: "We are delighted to support the event and encourage healthy lifestyles. The Wee Walk is a great and fun way to get across the five-a-day message. We are taking a little bit of the Wee Walk into our showroom and hopefully this taster will encourage the good people of east central Scotland to take part."
