Intervals are hard, circus could be fun?

I did my intervals last night and they were mightily difficult. At the risk of sounding like I'm always complaining right now, I don't think the convenience of being out of the cold and the dark, and being able to get home easily, was worth it - speedwork outside with the group is preferable to speedwork alone and on the treadmill.

You can say I told you so.

I struggled maintaining the pace with heart rate in the upper 180s and low 190s for more than 5 mins at a time.

But, all good.. two weeks til my next 5k time trial and I feel confident these efforts are going to fuel me going below 30 minutes.

In other news, the tumbling and acrobatics class I've signed up for at the national institute of circus arts starts tonight. It's to help with my core strength and hopefully add a bit of fun to things as well, though right now I feel terribly nervous!
