Target sub 35 after short break from sprint tris

[bertrudus]

I did 5 km park run on Saturday in 16:40 a new pb for me v pleased after 2 weeks proper break.
I lapped the 4km time at 13:22 which is quite accurate 4 km Tt given I blew up a bit in the last km. It was 50m short on Garmin so looks like I kept the same pace. A good marker to calculate the 2km reps from.

splits for the first 4 km were
3:15
3:21
3:24
3:22

Ultimately my goal is to improve 5km time (clost to 16 or even sub 16!?) do you think following the 10km programme will help this too ?

Thanks
