Yesterday I ran 6.2 miles, the longest distance I have managed during my training so far. Before this I kept hitting a wall. Frustrated, I called on my friend who ran the London marathon this year for some advice.

She was pleased to hear I did have some decent trainers from Asics and a sports bra, but not so impressed I had been training without taking anything with me, not even a bottle of water. Apparently, you need quite a bit of ‘kit’ when running distances.

Despite my initial scepticism, I headed off with my shopping list to The Jog Shop in Brighton. And I have to take my hat off to her, because it has helped me double my distance and pace. So here are the essentials:

Bum bag – for iPod (I listen to Lady Gaga) and gels.

Gels – which you take every 20-30 minutes to boost your energy and stamina (you need to practice with these before race day, they can be a bit fiddly). They really work to keep you going just that bit longer.

Double layered socks – to help you avoid blisters; these also worked a treat. (Mine are from a brand called Hilly).

Water bottle – ideally you need one shaped like a donut – they’re easier to carry than your average Evian bottle.
