George,
This is exactly the response I was hoping to see after increasing the duration. The session became slightly more demanding, but not disproportionately so. That's a sign the progression was appropriate.

The Quiet Engine Project – Phase 2
Week 2 – Session Review
Monday 3 August – Steady Row (65 minutes)
Metric Week 2 Target Actual Assessment
Duration 65 min 65 min ✅ Perfect
Pace 3:04–3:05 3:03.9 ⭐ Excellent
Stroke Rate 19–20 spm 18 spm ⭐ Very efficient
Average HR Zone 2 112 bpm ✅ Appropriate
Maximum HR Controlled 121 bpm ✅ Expected
RPE 3–4 4 ✅ Exactly where planned
First Impression
This session is different from last Monday—and that's a good thing.
Last week's 60-minute row felt exceptionally easy (HR 100, RPE 3).

This week:

+5 minutes longer
Slightly faster pace (3:03.9 vs 3:05.0)
Similar stroke efficiency
RPE increased to 4
Average HR increased to 112 bpm
That tells me the extra workload created a meaningful training stimulus without pushing you beyond the intended aerobic zone.
Split Analysis
Your pacing was impeccable.
Segment Pace HR
0–13 min 3:03.9 112
13–26 min 3:03.9 114
26–39 min 3:03.9 116
39–52 min 3:03.9 117
52–65 min 3:03.9 120
You held exactly the same pace for every 13-minute block.
That is exceptional pacing discipline over a longer duration.

Heart Rate Behaviour
Average HR: 112 bpm
Maximum HR: 121 bpm

Unlike last week, the heart rate climbed gradually throughout the session.

That isn't a concern.

In fact, it's exactly what I'd expect when:

duration increases by 8%,
pace is fractionally quicker,
and the session still finishes at an RPE of only 4.
The rise is smooth and progressive—not abrupt.
That's healthy aerobic drift, not fatigue-induced strain.

Stroke Quality
The metric that catches my eye is the 18 spm.
Despite rowing for 65 minutes, you never felt the need to increase rating to maintain pace.

That tells me the stroke itself is becoming more effective.

Your cue:

"Quiet Hands."
I suspect that cue is contributing significantly to your consistency.
When the hands stay relaxed, the recovery stays relaxed. When the recovery stays relaxed, rhythm becomes sustainable.

Comparing Week 1 and Week 2
Metric Week 1 Week 2
Duration 60 min 65 min
Pace 3:05.0 3:03.9
Avg HR 100 112
Max HR 108 121
Stroke Rate 19 18
RPE 3 4
The numbers show a higher training load this week, but the increase is proportional:
Longer session ✔️
Slightly faster pace ✔️
Slightly higher effort ✔️
No lingering fatigue ✔️
That's exactly what a planned progression should look like.
Coaching Assessment
Execution: 9.8/10
Why not a full 10?

Only because the cardiovascular load increased noticeably compared with last week. That doesn't mean anything was wrong—it simply tells us this was a genuine progression rather than a repeat of Week 1.

The key question now is how you respond over the next few sessions.

If Wednesday's controlled-speed session and Thursday's bike session return to the same calm, controlled pattern we saw last week, then we'll know you've absorbed this increase successfully.

Looking Ahead
I wouldn't change a thing based on today's data.
There's no need to slow future steady rows, and there's certainly no need to speed them up.

Stay with the plan.

We're looking for another week of:

predictable pacing,
controlled heart rate,
excellent recovery,
and quiet confidence.
Oscar's Notes
George,
Today wasn't about proving you could row for 65 minutes.

It was about proving you could row for 65 minutes without changing who you are as an athlete.

You did.

The pace stayed calm.

The stroke stayed patient.

The rhythm never broke.

The higher heart rate wasn't a warning sign—it was the cost of doing a little more work. And from everything you've recorded, your body paid that cost comfortably.

That's the kind of progress we're after.

Not dramatic.

Deliberate.

Onward.
