From M4DW's website:
"In October the weather in Marbella, the south of Spain is still perfect, not too hot and not too cold, a great time for walking. We invite you, together with walkers from all over the world, to discover the unknown sides of Marbella during the 12th edition of Marbella 4Days Walking on the 5th, 6th, 7th & 8th of October 2023.
Plaza del Mar at the Paseo Maritimo in Marbella is the starting point for the 10, 20 and 30 km routes which will lead you through the city, nature and along the beach. On the last day, the 8th of October, you will walk the Via Gladiolo (gladiolus being the Roman symbol for victory) back to the Plaza del Mar where you will be welcomed with loud cheers.
You can participate on all four days but it is also possible to choose the days that suit you most. In short: a perfect opportunity for a holiday."
