1 Run off road at least once a week – style, cadence, feet placement will be different. Get comfortable running both up and down on trails and looking as far forward as you can see.
2 The run is hilly so make your training specific. Try a hilly fartlek for 40-60mins. Alternate hitting the uphills then the downhills.
3 You don’t have to be a mountain biker to do this race but try and ride off road with someone experienced beforehand to boost your confidence.
4 Don’t neglect your endurance – do weekly, longer road rides, up to 3.5hrs, at a conversational pace.
5 Practise bricks, e.g. a 2-3hr bike hitting the hills hard onto a 15min easy run. Or, 90mins steady bike onto a hard hill run with 3-6 x 2mins uphill.
