Starting this year's exercises I am a little overweight. So I needed to do some workout, and I thinked that running could be a good way to start. A good way to do it, to feel a little motivated, was to join the competition known as "Circuito do Fogo" (Fire Circuit), promoted by the Brazilian Military Fireman Corporation. In this competition, you can either walk 3km or run all the way till the end, in a total of 8km. Running competitions have become very popular among brazilians. But there is a downside. Sometimes, when some people are tired of running and choose to take a walk, they stay all over the road, making difficult to other runners to keep the pace. If you are tired and have to take a break (like me), stay on the right side of the road, leaving room to other people keep running. Another problem is related to the amount of garbage that is thrown in the streets. If you can't find a trash can in your way, hold your empty water cup until the end line. Then you can dispose of it properly. Besides the problems, running is a great exercise, and the competitions provides some extra motivation!
