Using triathlon training to build aerobic strength for running

Definitely not.

If you want to do triathlons, however, then go for it.

Join some cycling and/or swim clubs.

It might help a little bit, but just note: none/very very few of the top elite distance runners put in a huge volume of bicycling or swimming. The best way to get better at running is by following a good running plan.

It depends what your goals are, what your schedule allows, and how your body reacts to training.

All things the same, a runner who bikes and swims for two hours a week is going to be in better shape (aerobically and running) than the runner who isn’t.

But, could your body handle just running an extra hour a week? If so, that’s probably the better option.

If you’re like me and running mileage gets you injured, then biking and swimming is your aerobic base, and I only run for speed workouts.

So, in short, it depends. You sound motivated which is the most important thing. And, as a 15 year old, you have the time to try out many different training routines. Not everyone is the same so don’t be afraid to experiment!

Unless you're going to make a good living off of running...in other words, Olympic caliber, then do Triathlons. It'll be more enjoyable having multiple types of training and you'll be in better overall shape.

History has shown you can still be a fantastic runner and train in multisport events.
