To offer myself a variation from solely endurance work I felt I needed to include interval training.
So I prepared myself for short sprints on my turbo trainer early this evening.
I used no music or audiobook to keep me motivated or distracted.
Instead I focused on peddling fast.
I set myself a straightforward workout of 10 x 30 seconds with 1 minute recoveries.
All I knew was I would sweat.
I got my head down and powered the pedals down and back.
After the first interval my breathing was heavy and my core temperature had risen.
The minute of easy cycling afterwards felt fine, although it passed quickly.
I tried to stay to a rhythm for each interval.
My long hair flapped in my face, but I ignored it and blew out hard.
My quad and calf muscles were heavy but I knew I could finish strong.
I checked my speed several times to ensure my effort matched the output.
None of my 30 second bursts fell below 32 mph.
The maximum speed recorded was 35.5 mph.
I sweated as much as I do when I cycle for over an hour.
I finished my 15-minute workout with a short walk, exhausted but satisfied.
