This morning my resting heart rate was raised by 10% and I did feel fairly tired. I committed to a swim and luckily on my programme I was timetabled for my steady endurance swim with no intense lengths at all. The warm-up 200m was the slowest I've done for many weeks (although still within 5:30min) and as I started the first of four 800m sets I wondered if I would finish.
Of course I did see it through although my average pace was slow. Naturally I fatigued during the session and the current in the pool is evident in the castellations of the charts. My weakening strokes are clear but actually at the beginning my stroke count per length was pretty good; I was making an effort to push off!
I'm sure that I'm just generally tired due to the longest running week I've had for around 10 months. Interestingly in Week 4 I did a similar swim after a long run and performed better than I did today, but I didn't have as much tiredness accrued from the week's activity.
It now seems important to start next week with a rest.
