Just back from giving it a shot. Notes:
-went out way too hard, need to reel it in and try for a negative split maybe
-couldn't get on top of my breath, potentially just not fit enough
-horrendous stitches
There's still time! Enjoying the process if nothing else
Viability survey:
Can I squeeze out my 20min 5k in 2020?
PB: 20:21, this year
Recent runs:
14/12 - 5km easy
13/12 - 7.47km @ 4:34/km - felt hard
10/12 - 7km easy
2/12 - 4.7km easy
1/12 - 6x1km @ 4/km 0.5km rest between
28/11 - 4.8km easy
25/11 - wu, 4km TT, cd (managed the 4km in 16:17)
Feels like it might, just might, be in reach. I'm regretting that 8 day gap a lot.
