A time predictor might help you with your pacing in the Canberra Times 10k.
According to the time predictor my 90:50 half the other day equates to a 40.45 10k.
So I wouldn't expect to break 40 (yet).
In the CTFR I find I lose about 30 seconds between the 3k and 6k marks. (Because, not being especially fit, I slow dramatically up hills at present.)
To run 40.45, my pacing plan is therefore to hold myself back to about 4:00 per km from the start to the 3km mark, 4.10 per k to the 6k mark, and close to 4.00 per km to the finish.
If that's not too scientific for you, you too could have a go at working out your best pace based on your times for other runs.
