40 min 10km. Am I on the right track?

[Tigerdale]

Hello TheEd,

I recently did a 5km time trial about 2 weeks ago at the end of the last cycle and my lap splits were as follows:

Distance______Time____Lap time__HR
400__________1:42_____1:42_____144
800__________3:28_____1:46_____161
1200_________5:14_____1:46_____166
1600_________7:00_____1:46_____170
2000_________8:47_____1:47_____171
2400_________10:31____1:44_____174
2800_________12:18____1:47_____173
3200_________14:06____1:48_____174
3600_________15:55____1:49_____173
4000_________17:38____1:43_____176
4400_________19:18____1:40_____177
4800_________20:55____1:37_____180
5000 (200m)___21:38____0:43_____183

I also have a club track meet on the 14 of Jan, in which there is a 5km scheduled.
Just wondering whether I should do a hard 4km or 5km here or stick to what would be a 5km paced run on the program?

thanks,

Dale
