Hill Training

They say that if you want to increase your running strength, nothing is better then hill training. Now, being a runner for over a year, i thought i could give it a chance and see if it works for me. Now, comes the tough part, since i live in mumbai, there are no hills apparently. To do it, i have to do it on any of the fly-over roads. I found one, which has no traffic in the mornings, which means clean air, it has a good sidewalk, which means no chance of getting struck by vehicles, all in all a good package as a hill. The incline and decline makes up around half kilometer. On the first day (yesterday), i did six loops at hard effort. I try to maintain the same speed at both incline and decline, which means hard effort going up and easy while coming down. I wish to do this workout once a week, followed by a rest/easy day. Honeslty speaking, it was tough on day one, the qauds feel the effect of the climbing, but no big pain. Today i did an easy 5Km at very slow pace to recover from yesterdays workout.
