Now, it doesn't have to be a run you map.  You could map your cycle or your walk.  

With the advent of satellite navigation lots of lovely, hi-tech equipment came on to the market for sports people.  They're great but for people with small wrists, small budgets or who are just starting a fitness regime, Garmin Forerunners are not always an option.

So, say you go out and about on your favourite mode of transport - be that legs or a bike - you can get back home and see how much ground you covered.  Or should you have a specific distance goal in mind, you can plot a route out beforehand.

If you're serious about your training and go on holiday or a business trip - you can log on  and see what routes the locals use - be that in Uzbekistan or Manhattan.
