I'm doing it this year with a couple of mates. It's the first time any of us have taken part in it though. So no tips from me I'm afraid!! lol. Out of our lil team I'm the only one with any distance running experience. How're you finding the training?
I'm an insurance broker (for my sins!) and one thing I would recomend is making sure you check the section about 'medical expenses' whenever you get quotes for travel insurance from anyone. With a lot of the online companies, you might think you're getting a great deal on price but when you check the cover for medical expenses you realise why. I looked at one recently that only gave a maximum payout of £250. This might seem ok but if you were to break a leg (for example) whilst abroad and were unable to fly home this would have to pay for all your costs, possibly including return flights, for as long as you're stuck there. As you can imagine, that's not going to stretch far, especially if you're there as a couple etc.
