A series of unfortunate events = despair

Well I haven't had much luck with this session at all this week. I wanted to do it on Monday, but instead had to do the Fartlek session at School and then head straight off to a Cricket match (which we lost!). That's why I didn't to this session on Monday if you were wondering why. Anyway, no problems at all as I could do that session today. Well at least I thought I could, and I was going to use a nice loop round the houses and river which was flattish and fast. Walking back from School however, this path was blocked off and this presented a major problem as the only way I could get past was by going into the river! Major problem number one encountered but that wasn't going to stop me doing the session, and so I decided to do the same course as last week. So after a good warm up with strides etc, I was good to go.
First Rep: Very, very strong headwind which made running really tough. Not to mention the big hill which takes a hell of a lot out of both your legs and lungs. Still, a good first km by all accounts in 3:39.
Second Rep: Again into the wind and another really tough climb. My legs felt a little jaded as I tried to run hard off the top of the hill but I still felt to be on for a good time. But then I saw it ahead, blocking the road, a massive digger next to a sign saying road closed! I couldn't believe this so, after a few seconds of messing around, I turned round and decided to run where I'd came from to top the effort up to a km, which ended up being 3:43 (including few seconds messing around).
Third Rep: After the last effort, I didn't really know what to do, as heading for home would only mean I would get 4 efforts in. Alternativley I could run another one out into the headwind and then one back. No thanks I thought. I ran back towards home and then turned at a sign. Not a bad rep at all, 3:37 in fact.
Fourth Rep: The last one I decided. Seeing that digger really had knocked the stuffing out of me as it practically destroyed the session. So I went, up the hill and to the bad junction where I had to check for traffic, although I was so angry I felt like just running on for the hell of it and taking one for the team. The Garmin countdown timer eventually came, 5...4...3...2...1. I look at my watch and 3:45 is dominating the screen. I feel disappointed, but relieved to have got at least 4 efforts in, and I don't even feel tired which is the most annoying thing. Someone obviously didn't want me to do this session!
So a frustrating day all in all. Still, some good times recorded on the efforts which I actually wasn't interrupted on by hills or junctions or tossers sat in diggers doing nothing (oops!). Life goes on and to compensate for the bad luck I've had, I went for a nice 3 mile off road run meaning 6 in total for the day and 28 for the week so far. I feel as though I will definitley do this session on a Monday from now on, as my legs weren't ready to smash the reps out after a rest day yesterday. Surely tomorrow can't go wrong now after the number of misfortunes I've had today!
