Today's episode is a guide to creating a marathon race fuelling plan. What do you need, why and how much? When are you going to have anything and how are you going to make it happen?

I step through fuelling and hydration and what you need to consider and practice now in your training so that you don't get caught out on race day.

Your plan doesn't need to be overly complicated but if you don't think it through in advance then you risk putting all that training to waste and not getting the outcome you hoped for.

If you need more detailed advice and help planning your nutrition, you can learn at your own pace with the 'Master the marathon' course available at www.therunningrules.com/master-the-marathon
