Look ahead to save gas! Tackling hills on my bicycle has taught me a few things about how to extract the best fuel economy from my car. The first time I saw the gas pump register $120 after filling up gave me a jolt of motivation to get the most from each expensive tank of gas. A while ago, I bought a digital speedo for my bike, primarily to see how far each journey was taking me. But once out in the hills, watching how fast I was travelling up the big long ascents soon took my interest. I realised that to increase my speed by even one or two kays an hour while I was climbing required a lot of extra huffing and puffing on my part. Conversely, when descending, it was easy to add another ten kays an hour by putting in the same amount of effort. On longer rides, I began saving my energy for where I was going to reap the biggest reward.
