I am a 15 year old girl and l wanna run a marathon with a friend from school. We both do cross country and track. We have already started training, and the longest we've run so far is 13 miles. We still have 5 more months to train, so l think we'd be well prepared. Do you think it is still safe being at such a young age?

Anybody can run a marathon at whatever age they may be, age does not matter, as long as you are fit and healthy and want to run a marathon. Just drink plenty of fluids and eat a good meal the day before the fun. Also do plenty of stretches before the race, since it is a long run. Are you going to run in the L.A. Marathon? Good Luck!

l do not know you should ask your doctor.
