This was a couple of weeks ago.
Only ever done 5ks in sprint triathlons, so off the back of swim and bike. Fastest i've done for the 5k in a tri is 20.15, but reckon i could easily go sub 20 on a standalone 5k.
Last time I did steady state, few months ago, it was around 25 mins, don't do steady state anymore, I'm a lot fitter though....
17.45 as a PB before I got hit by a car about 2 months ago. Went for a run again today to see how much i've lost in speed and can still manage an 18 minute 5k.
It helps to be skinny as **** for this haha.
Never been timed properly, but it's definately under 19 minutes!
