My Road to TOWaterfront 42K


📝 Where was my RPE?

I think yesterday’s short hike on hilly terrain likely contributed to my relatively high RPE on today’s 40-minute Easy Run. Yes, I did it fasted, and yes, the temp crept up during the run, but I could feel the residual fatigue from the “leisurely” hike. Thank goodness I had Drum Buddy Beats on board.

🎯 Coach’s Corner

Execution vs Plan

  • Planned: Easy 40 minutes in Z2, with steady cadence and relaxed aerobic effort.
  • Executed: ✔️ 40:17 at 6:55/km, Avg HR 141 bpm, Pa:HR at 5.24%. The hike fatigue elevated RPE, but HR and pace metrics show you stayed right on plan.

Environmental & Fatigue Context

  • Yesterday’s “easy hike” carried into today, bumping up perception of effort.
  • Rising temps added mild extra stress.
  • Despite those, cadence and HR stayed consistent → aerobic durability in action.

Overall Read

This was a smart, controlled run: you let the data show the truth when RPE felt misleading. That ability to trust cadence and HR zones instead of “feel” on a fatigued day will pay off in the marathon.


✅ Takeaways

  • Execution win: Perfect Z2 despite high RPE.
  • Highlight: Pa:HR at 5.24% shows aerobic base holding even on hills.
  • Watch item: Non-running “active days” (like hikes) can tax recovery more than expected.

Lesson: Drum Buddy cadence anchor prevented drift when RPE felt high.
