1. Get the balance right
When you've got a big physical challenge on the horizon, there can be a temptation to throw yourself head-first into your preparation.
Our advice is always to start slowly. You need to find a balance between training and the rest of your life. Preparation requires discipline but you should structure around your life, not vice versa.
Don't train hard every day, as you'll soon get tired and bored. You don't want your preparation to feel like a slog.
2. Mix it up
Stimulating your mind and body is vital to preparing for any sort of challenge. If you know that you're facing a big test of endurance, then you've got a wealth of options to boost your fitness.
Walking, jogging, cycling or swimming are all great at building up your levels of stamina for the task ahead.
Try different things. Keep yourself busy doing all types of exercise. Mixing up your training will make your journey all the more enjoyable.
3. See the big picture
Taking on a challenge is tougher than you think. Even if you're a fitness fanatic, you'll likely be using muscles that you haven't used before. You might ache in unusual places and there will be a few ups and downs along the way.
Some days you'll really look forward to training. Other days you'll wonder whether it's worth it and if you're actually making any progress.
See your preparation as a big picture. Each week you paint a little bit more to make it more complete.
