Getting Started on Training Plan

[amorts]

Ok I attempted to do the 6 x 1k on Tuesday night and although I my legs were going all out. My heartrate wasn't moving anywhere. Could have been an indication of overtraining?

So I had 2 days rest and went out on Thursday instead.

Firstly the splits from the 5k on Saturday;
1k 03:29
2k 03:36
3k 03:50
4k 04:00
5k 03:53
Var 00:19
Total 19:07

Next the splits from last night, again although hills were involved I felt that these times are a good indiction of my current fitness.

6 x 1k with 30 secs rest
1k 03:51
2k 03:54
3k 03:57
4k 04:01
5k 04:17
6k 04:08

Thanks, 1/2 marathon 1 week on Sunday.
