Since you have never run before try different events to find what you like and do best, your size is not a good indicator of your abilities, and you might be a good jumper not a runner.
Follow your heart and your dreams will come true
You should run long distance! I have a friend that is 6'3 and he runs long distance. I also recommend you either doing hurdles, with the long legs, high jump, with the height, or long jump! I also did track. I'm 5'5 and I ran 800 relay and 200m dash. Good luck!!
800 and below or field events (shot put, discus)
