I found the 25 minute run hard work tonight. The last few I've done 3.3km but tonight I only managed 3.0km. This may have been because of instead of playing my running playlist I put my ipod on shuffle so ended up with quite a few slow songs.
On the plus side I never doubted that I could finish the 25 minutes. Looking forward to week 8 now! Can't believe I've got this far
