Im a 15 year old male who use to go to training for sprinting but recently had to stop going cause of it closed down. I have a sprint time of 11.24seconds and want to keep it coming down but i am finding it impossible to do so. Can anyone just give me ideas of what i can do to get my sprint speed higher which does not involve running on track? I am stuck and really need ideas on how to get a higher speed and faster time!
