When I was doing the plan I used map my walk to track stuff like distance and speed and it said I was around the 8min/km mark, since finishing I'm using bluefin and my own music which is around 108-111 bpm and attempting to run to the beat and bluefin says I'm around 7min/km mark.. I don't think I'm that quick!!
I may try going back to doing speed once a week as part of the challenge now!!
If you stick with one device for recording your runs it will be easier to see your progress. I use Map My Wotsit and its fine. There may be a small time difference compared with the podcast I use as it bounces around the satellite but as I won't be competing against Mo Farah I can probably live with that 
Ha excellent! Thank you! I'll stick to bluefin for now then, it says I'm going quicker! I haven't changed anything like where I put my phone or anything so I don't understand the difference! I just like to know for interest really and also for choosing songs!
Speed - How Speedy?
Treadmill people (or outsiders) - what speed do you run?
Need for speed!!
do I really need to knock 2 minutes off my km pace?
For Graduates: What was your speed at (or near) the time of graduation?
