National Fitness Day is aimed at highlighting the role physical activity plays in helping us all lead healthier, happier lives.
This year's event, on September 25, will see thousands of events being held the length and breadth of Britain to encourage the population to keep fit.
But many people in Wales are already acting on the fitness message by getting out and getting active.
Participation levels have been on the rise throughout the country in recent years and the signs are there for all too see.
Travel any distance along Wales' roads and you will see dozens of brightly coloured lycra-clad cyclists pedalling for all their worth.
Swimming pools aren't just places to go and splash around with the family for an hour these days - although that's a healthy and fun activity in its own right.
Lane swimming sessions are often the busiest in pool timetables as people take advantage of the all-round, non-impact workout offered by swimming, or are preparing for one of the many triathlons which are now hugely popular throughout Wales.
And the rise of parkrun means you are never far away from a choice of free-of-charge, friendly and welcoming opportunities to get out and run for fun in some of our country's most beautiful locations on a Saturday morning.
Running has become a hugely popular way for people to not only stay active but also widen their circle of friends.
Social running clubs are on the increase thanks to organisations such as Run Wales, set up in order to increase and support participation throughout the country.
