Watch Sisters Laura and Nathalie Love Train for a 15K Race

[Laura] I'm Laura Love.

[Nathalie] And I'm Nathalie Love.

We're training

For a Toronto 15K.

(energetic pop music)

I live in New York and Nathalie lives in LA

so it's hard, obviously, to run together

and train together.

[Nathalie] But we've been doing it through

these Nike apps.

So we can compare, we can send each other

our runs for the week.

And she's faster than me.

Just a little bit.

In this experience I've learned

how deeply competitive my sister is.

And how strong she is.

She's always motivated me and inspired me

to be more fit.

I really could not have done it without her.

The most exciting part of this process for me

was learning how to run and knowing that I can run.

It gives a different kind of energy

I've never felt before.

It makes me feel really high and good.
