Right the C25K app is now called 'Ease into 5k'
Pros: you can enter your weight, so calories burned is a true figure.
You can enable GPS.
You can enter how you feel that day, to see if a pattern emerges for bad runs, if you always have a bad run after a late night then you can adjust your days.
You can upload to Twitter and FB.
Cons: Abrupt commands, trust me I hated this guy!!
Get Running
Pros: lovely lady gives you warnings 'get ready to run in 10 seconds' encouragement 'you have just 30 seconds of running left' so if you're on a treadmill you can get ready to slow the machine down.
Play your music in the background, the music turns down when she talks to you.
Cons: can't adjust music without leaving app.
After a few weeks the encouragement could get a bit much!
So with all the pros you would think the ease into 5k would be my choice, however it's not! Don't underestimate the power of encouragement!!!!
It's also easy to fool the ease into 5k app that you did your run, then enter your data and post that way.
Those of you using Nike+ can use that instead for tracking speeds etc!
