Building back my base + 10k training program

[goldfeld]

Hello

Ok, so I did the 1k laps session (6 laps), here it is:

4:25, HR up to 171, rest 70 secs, HR dropped to 119.
4:17, HR 178, r. 80, HR 124.
4:14, HR 179, r. 80, HR 130.
4:22, HR 181, r. 80, HR 130.
4:18, HR 182, r. 80, HR 133.
4:08, HR 185, r. 80, HR 127.

Is my Heart Rate slow in dropping? How do I improve this?
What's my aim for the 5k paced run?

Cheers,
Johnathan.
