From 8.4 km to 13.4 km
5.0 km · -0.2% average · 28.7 km/h · 146 bpm, peaking at 154
The flat stretch near Widford early on shows you settled into a steady 29 km/h, but your heart rate was running well above where it sat for the rest of the ride—that's a sign you went in harder than the terrain asked.
