TCS Toronto Waterfront Marathon Recap: The Four Acts of the Marathon

Act I – When Plans Meet Reality Something felt off before I even crossed the start line. I’d eaten my pre-game bread and jam, almost finished my Maurten 320, and was feeling calm, confident, and ready. Then, suddenly, it hit – a strange rush. Not excitement, not nerves. Something chemical. My body flooded with energy

Weekly Recap – Taper Phase (Oct 7–12, 2025): Ready, Not Restless – Fatigue with Purpose

My Road to TOWaterfront 42 K 🏁 Opening Reflections Taper week arrived with its usual mix of too much energy and not quite enough spark. Every runner knows this uneasy balance-legs that feel both light and sluggish, fitness that’s fully loaded but still under wraps. This week, I reminded myself: taper isn’t about rest-it’s about

Tough Taper Long – Taper Phase | Run 5 (Aerobic Endurance with MRP Finish)

My Road to TOWaterfront 42 K I woke feeling ready and fueled, but that spark dulled once the run got rolling. Pre-run mix: Maurten 160 (1 h before). My plan was 160 @ 40 min, 100 @ 70 min-but I only had 160 gels on hand, so both were 160s. Possibly overkill, but it got

Somewhere between kilometers 3 and 5, my mind drifted to race-day visuals – where I’d be at 10 K, 30 K, and beyond. Could

Gloves Time! – Taper Phase | Run 3 (Speed Workout)

My Road to TOWaterfront 42K The temps plummeted to comfort levels for running.. Gloves were non-negotiable. This was a short but spicy speed workout, and I felt dialed in from the warm-up. My Drummer Buddy pulsed through the accelerations, and cadence snapped to attention. Each two-minute Z5 rep was a measured surge, not an all-out

Fatigue Fun…Oi. – Taper Phase | Run 2 (Aerobic Endurance/Strength)

My Road to TOWaterfront 42K Tired all day. The shift to late-day running always takes me a session or two to recalibrate. I sipped some Nuun before heading out, My Drummer Buddy on board, cadence steady. Not entirely sure if my chest strap HRM synced – the data might be from the Forerunner 235’s optical

Aerobic Endurance/Strength – Taper Phase | Run 1 (October 7 2025)

My Road to TOWaterfront 42 K A calm, easy start to taper week. I sipped 500 ml of Nuun before heading out into a light, energizing drizzle. Conditions were warm but comfortable-18 °C with the kind of mist that makes you feel quick without trying. My Drummer Buddy piped steady beats through my Shokz, stepping
