It is important in any endurance event to keep eating and drinking to maintain energy and hydration levels; the same applies to the training walks leading up to the challenge. Keeping both energy and hydration levels high will make strenuous portions of your walk feel far more manageable. Use your training walks to trial different foods and see what works for you, remembering that the predominant fuel you will need is carbohydrates (bread, pasta, potatoes) prior to the event to get your fuelled up before you head out, whilst taking a variety of snacks with you on the walk itself.
During any trek, after around 25 - 40 minutes, dependent on your pace and ﬁtness, the predominant fuel source you will start to burn will be fat rather than carbohydrate. As a result of this, we recommend that snacks such as nuts, cereal bars & ﬂapjack and fruit are a great way of keeping sustained as you walk.
