Dangerous situation

When I was young I went on holiday to a little town between (the) mountains. I loved that place because I like riding bikes on mountains.

One day, I went to ride was riding my bike. It was a sunny day and I was very excited because I wore was wearing my new helmet. Suddenly, while I was riding on my bike, a huge and, ugly dog started to run running after me. I started to run pedaling faster (on my bike), but the dog didn´t stop run kept running after me. (you could also say, "kept chasing me.")

Then the dog started to bark and jumped near my left leg. I was very afraid and I fell off my bike.

While I was laying on the floor ground, the dog dissapeared. Then I checked my body to see if all was in order and I relaxed. I was alright !

If a dog runs after you while you are riding a bike, the worst thing you can do is start to run pedal faster. My advice is that you stop as soon as possible.

I understood everything you said. Great job! I hope I was helpful.
