My lower back has flared up. I worked at home on Tuesday and I think the chair I used is the main culprit. It was a bit stiff on Wednesday, but didn't really hinder my running. Yesterday it was somewhat worse, and due to the discomfort combined with a deadline at work, I didn't run.
So I woke up this morning, got moving and knew immediately it still wasn't the best, but I have run through lower back pain before so thought I'd give it a try. Ended up being a pretty difficult run. Quite painful and slow for the first 4 km or so. Then I stretched my legs and back when I hit Komazawa Park, and it improved a little. I finally got my pace better than 5:00/km, but not much. Still felt like I was hobbling. I did a couple of laps only and then after a toilet break headed home. When I was fully warmed up I was moving OK, but it was a bit of an effort. My heart rate was higher than it should have been for the pace. By the time I finished, my right hip was hurting, probably because of an altered gait. I should have known better. Here's the breakdown.
From a training perspective it wasn't complete write off, but I hope I have not set myself back further by pushing through. I have a tendency to do that, especially when, as now, I am trying to lift the workload. Let's see what tomorrow brings.
