This is a rest week, it's also best part of 4 days since my last run. So the idea was to not go far but make a bit of effort. Last winter I did intervals along the park and now I'm feeling stronger I thought I'd try that out.
After a warm up from home I attacked the 1km straight with fair intensity but not as fast as might have been possible. After all I didn't want to set off any of my recovering injuries. My pace for that was 4:17 min/km which is my 4th best time. The average heart rate was 182bpm. The last third of the segment was at a heart rate of around 155bpm which suggests that I could go a little faster. Conversely at the start at was over 220bpm. Is this possible or is it misreading?
Links like this and here suggest that the band and the chest contacts might be too dry until a good sweat builds up. That's good as I'm sure 50 year old myocardium can't move that quickly!
After the 1km effort I headed home with some streetlamp and tree fartlek both on the level and uphill.
