Speed Session Fail

I stole one of @Mia79GBR sessions for speeding up her 5k. its as follows:

5x 4 min @10k pace off 1 min recovery, followed by 5x 2min @5k pace off 1 min recovery.

I dutifully put it into my garmin last night, setting 10k btw 7:50 and 8:00, and 5k@ 7:10- 7:20...

Was running the session ok, though on the 3rd interval was starting to feel it, and really struggling to keep pace.  I even allowed myself 3 minutes rest before starting the 5k intervals... 90seconds into the first one, I gave up... walked home.... totally wiped out!!  tee hee!  I guess that proves 1 of 2 things:

1) you shouldn't do speed work 2 days after a 10k

2) I shouldn't do speed work on my estate where it is so easy to stop, and anywhere is less than 5 min walk home... 

So, here is what i did manage

5 min warm up at 9:56 - this is slow for me at the moment, so I should have known something was up...

4 min 10k pace intervals

1. 8:01

2. 7:53

3. 7:57

4. 8:03

5. 7:57

I guess 5 half mile repeats with only 1 min recovery was actually pretty good going, given I've been doing similar sessions with a much longer recovery between repeats.
