I have found a technique that works for my running and cycling. I usually try and break the hill into thirds.
Obviously, all hills vary in terms of gradient and length, but I seem to have found a good method below:
First third you go slow and steady, I often count 1,2,1,2 and match it with breathing.
2nd third - try to build up the pace, if you have regulated well in the first third, this should come easier.
Final third - build pace further, remembering to keep counting all the way through.
Having built up the pace, I have found it easier to then go over the crest of the hill and keep going.
In essence, its all about the approach, mentally and physically to hills. There are so many factors including personal fitness levels, gradient and length of the hill. However, I can guarantee the way you battle the first sector of the hill generally depicts how the rest of it will go!
Some hills I have such a negative attitude towards, but recently I have tried to ditch it and just think of my above method....the result? I have got up the hills, no stopping half way or at the top...!
YOU CAN DO IT!
