Running Highs and Lows

I did the Longleat 10k last weekend. It was the toughest 10k I’ve done yet, and possibly the coldest and certainly the windiest. It was also the first non-charity race I have done. Despite everything I couldn’t help feeling a little low about the race. I finished it in a reasonable time for me of 1hr 03, but the usual euphoria I have at the end of a run just wasn’t there.

I assumed the course would be off-road or at least partly off road, but no such luck. The hills were unrelenting and the my mind started playing games. I knew I could do the distance but I was feeling very negative about the whole race. It probably didn’t help that the race opener - a former London Marathon winner - announced that it was a hard course just as we were about to start.

The countryside around Longleat is amazing and I was really looking forward to running up some of those grassy hills. Maybe I was just not in the right mood. Maybe it was the food I had eaten. Maybe I was missing support. My family normally come along and cheer me on. Maybe it was just the cold and the wind that was making me feel negative. I started questioning myself. Why am I doing this? Maybe I was just having a running low. I found this thread on the UK Climbing forum which talks about running highs and lows. Anyone else had a running low? 

I need to find a good 10k race off road. Any suggestions?
