8.03 km Morning Walk – Aerobic Endurance Session

I headed out for a walk this morning, covering 8.03 km in 1 hour, 15 minutes and 5 seconds. It was a controlled session from start to finish, with a steady pace and a relatively low average heart rate.

The main aim was simply to get the distance in without turning the walk into a harder workout. Looking at the numbers afterwards, it was a good aerobic endurance session with very little time spent at higher intensity.

8.03 km Walking Session

• Distance: 8.03 km
• Duration: 1:15:05
• Average pace: 9:21 min/km
• Average heart rate: 118 bpm
• Maximum heart rate: 141 bpm
• Calories: 547 kcal

Very Consistent Pace

One of the things that stood out was how consistent the pace remained throughout the eight recorded kilometres.

• 1 km: 9:26
• 2 km: 9:05
• 3 km: 9:33
• 4 km: 9:26
• 5 km: 9:22
• 6 km: 9:13
• 7 km: 9:19
• 8 km: 9:27

The fastest kilometre was the second at 9:05, while the slowest was the third at 9:33. That’s a difference of just 28 seconds, which shows that the effort stayed remarkably controlled over the majority of the walk.

Heart Rate and Training Effect

The heart-rate figures also suggest that this was primarily an aerobic session. My average heart rate was 118 bpm, with a maximum of 141 bpm.

The activity recorded:

• Extreme: 0 minutes
• Anaerobic: 1 minute
• Aerobic: 56 minutes
• Fat burning: 17 minutes
• Warm-up: 0 minutes

With just one minute recorded as anaerobic and the vast majority of the session in the aerobic and fat-burning categories, this was much more about sustained movement and endurance than pushing for speed.

A Useful Endurance Session

Walking more than 8 km at around 6.4 km/h makes this considerably more than a casual stroll. The pace was brisk enough to provide a worthwhile cardiovascular workout while remaining manageable for the full 75 minutes.

What I particularly liked about this session was the combination of distance, pace control and heart-rate management. There was no need to force the pace. The objective was to keep moving, maintain a sensible effort and complete the distance, and the numbers suggest that worked well.

The Takeaway

This morning’s 8.03 km walk was a good example of how a longer, controlled walking session can complement harder exercise. It provided more than an hour of continuous movement, covered a meaningful distance and kept the cardiovascular intensity under control.

8.03 km, 75 minutes and an average heart rate of 118 bpm. A solid aerobic endurance session to start the day.
