Speaking as someone who has no idea what the fuck he's talking about - all the literature I've read suggests changing up your routine - change 3 runs a week to a swim, a leg session at the gym (or a general leg-oriented workout) and a run. I read that's the best way to break a slump. But, my personal best for a 5k is around the 40 minute mark, as I usually need to stop and lie down and vomit halfway through, so take my advice with a pinch of salt! Well done Gladstone, pretty awesome achievement(s)! xx
