Runner time calculator

km mile
Dist.:	Marathon Halfmarathon 10km 5km
Pace (min/kmmi )
Speed ( km mi/hr)

Once upon a time I decided to play with different distances and paces required for specific time. Plus to this speed, pace, miles, km... - finally I didn't find as good calculator as I wanted and decided to create my own.

For time and pace you can use dot (.), comma (,) and colon (:), we understand.

Enter, ENTER - watch!

I've tried and liked it. Probably it can be useful for you too.

If you've found any bug - let me know, I'll try to fix it.
