Shouldn't this be a taper?

I know I should be tapering this week and I guess I am, but I feel I just need to be getting out consistently after almost a month of sporadic running. So on Tuesday night, after the girls went to bed -- notice I didn't write "went to sleep" -- I got out for a 5K run. I had intended to go for 8K but I knew I had to get home quickly to help finally get them to sleep. My legs felt a bit heavy but I finished it off in about 20:40. Obviously that is a bit slow for my liking but it was good just to be running. I am starting to get concerned again about my hamstring, it just never seems to want to get back to 100 per cent.
