In reply to JuneBob:
Unsure if question is serious or not? (no offense)
1) Add hills to your training
2) Add fartlek to your training
3) Go faster on the downhills to make up lost time
4) Slightly more technical, but maintain your cadence (i.e. number of steps per minute) when ascending. This will mean a shorter stride length, but try to keep the number of steps the same. Practise with a metronome prior to racing. Drop pace, maintain cadence (meronome should be consistent for level/uphill/downhill).
Again, no offense meant, but if you have to ask how to train for inclines, your present training plan must look quite odd. If you ran inclines often you wouldn't be asking what you asked, as you would know what was required.
