Yesterday was my first mighty hikes marathon, I was blown away by the whole event from start to finish. Kane, Gower Peninsula

The food was amazing, the toilets all clean, the cups of tea were amazing!! Deanna

I hiked this marathon in memory of my late partner. It was, and will be one of the best things I’ve ever done. Phillipa

All the support was amazing! This was our first marathon and one of the most rewarding and emotional experiences I've had. Andi

The volunteers at the pit stop were super friendly, the selection of snacks was fantastic, the stewards along the way were full of smiles and encouraging words, and the finish was brilliantly set up (the food was delicious!) I've done other charity half marathon walks before and they didn't even come close to this as far as organisation and support is concerned. Claire

What a truly incredible day that was. EVERYTHING has been thought of by the organisers. To all the beautiful people I met during the course of the day, thank you for sharing your amazing stories and general banter. It made the whole experience so enjoyable, and the end very emotional. Gary

Amazing day with my sisters doing our first Mighty hike! Was tough going but the organisation and help was second to none. All the food and snacks and encouragement from everyone was awesome. Lynsey

I can't get over how well organised this was today. The event team were amazing from start to finish and really looked after every one. The pit stops were fantastic, food was gorgeous and the smiles and cheers of support helped to push us through. Thanks so much for making it so special. Rosemary

Thank you for the amazing organisation of today’s event. Nothing bad could be said. Big shout out to my Macmillan Nurses Christina, Astra and Helen. Life wouldn’t have been the same without you. Michelle

Another fantastic Mighty Hike, loved it from start to finish. No other event is so well organised, from the welcome to the personalised finish line. Thank you for having us. Kate

Thank you to all the lovely marshalls and event organisers for an incredible day. The views were unforgettable and it was so great to chat to the kind and friendly people we met along the way. We'll definitely be back! What a buzz crossing that finish line! Kaija

4 steps to wellbeing
Sleep well

A good night's sleep is an essential foundation for a healthy lifestyle, effective training and weight control.

Train slow

Low-intensity training is easier for you, reduces the risk of injury and helps builds an efficient aerobic system.

Eat natural

Cut out sugar & junk food, reduce carbs, eat natural foods and train your body to burn fat for fuel.

Get outdoors

Fresh air, natural light and reconnecting with nature all help to improve mental and physical wellbeing.
