Is my aerobic engine back?

A 14km continuous long run, with two 5K blocks in the middle, to find out how much aerobic fitness I've rebuilt since my best in 2021.

The answer is in the data: power held from 286W to 283W across the two 5Ks, while heart rate drifted just 2 bpm (144 → 146).

In this episode:
• The 14km long run, with check-ins along the way
• What heart rate drift tells you about aerobic fitness
• A slightly bigger training week banked
• First look at the Lab – my new training dashboard, now live on krruns.com

The Lab is the dashboard I've always wanted for my own training. It builds on Runner's Arc and tracks how fast I'm closing the gap on 2021. A full walkthrough video is coming soon.
