Was dreading this. Waited until late in the day where the temps drop slightly. I did a 10 minute warm-up and made my way to the start of a fairly flat 1km stretch of path for my 10 x 3 minute efforts with 1 minute standing recovery.
These went okay - I was sweating profusely but managing to cover around 920m to 940m in the 3 minutes running out and then back. One way was slightly more uphill, the other was more in the wind. Swings and roundabouts. Finished up with a couple of kms warm-down.
All up 14.1km running for the day.
