I've just completed wk5 r3 and although the last 60 seconds seemed to go on forever I felt really pleased with myself. However that all changed when I decided, rightly or wrongly to check how far I'd actually run and when I realised I'd only done 2.6km in 20 mins I now feel really deflated. Is this too slow? At this rate I'll never be able to do 5k in 30mins.
I think I need some advise.
