1.95 km in 13:30; run 2 walk 1

...which is an 11:11 mile pace, it says here, though admittedly only for just over a mile. And I've upped the intervals to two minutes running (which seemed a very long time) followed by one minute walking (which went by very quickly). It felt like quite hard work, but I also felt I could have gone on for a while. A little bit further tomorrow, to see if we can settle on a route that takes somewhere between 15 and 20 minutes.
