This is where you lost significant time - you were grinding at unsustainably low cadence on the steepest section. + + **Pacing Pattern Analysis:** +- **Start (0-26:40):** Consistent ~12-13 mph, 70-90 rpm cadence, ~150 bpm HR - good sustainable pace +- **Middle (26:40-35:00):** Speed holding ~11-12 mph, cadence still decent 60-80 rpm, HR climbing to 160s +- **Crisis Point (35:00-39:00):** Speed crashes to 7.3 mph, cadence drops to 46 rpm, HR maxed at 168 bpm - you hit the wall on the steepest pitch +- **Recovery sections (gaps in data):** Appears you had to stop/soft pedal briefly, then resumed +- **Final push (40:00+):** HR surged to 135+ but speed didn't recover - too fatigued + + **The Singlespeed Problem (38/20 gearing):** + + At 46 rpm on the steep section, you're at 60% of your average cadence. This gear is simply too tall for the 7-8% gradient sections. You're forced to: +- Mash at very low cadence (high muscular force per pedal stroke) +- This fatigues your legs faster than your cardiovascular system +- Notice your HR wasn't maxed out (168 bpm vs 181 max) - your legs failed before your cardio did + + **Where Time Was Lost:** + + Comparing to target 15:08 pace: +- First half (miles 0-1.4): Relatively close to target, maybe lost 30-45 seconds +- Steep section (miles 1.4-2.8): Lost 2:30-3:00 here due to the speed collapse +- The 39:00 mark crisis point alone probably cost 1:30-2:00 +- ### ⚠️ Critical Finding: Gearing is Your Biggest Limiter + + Your data clearly shows the 38/20 singlespeed forced you into an impossible situation on the steep sections. At 214W average power, you should be capable of ~10-11 mph on 7% grades with proper gearing (80-90 rpm). Instead, you were forced to 7.3 mph at 46 rpm. + + If you had gears allowing you to maintain 70+ rpm throughout: +- You could likely sustain 230-240W instead of 214W (less muscular fatigue) +- You wouldn't have the catastrophic slowdown at 39:00 +- Estimated time with same 214W but proper gearing: 16:30-17:15 +- With 230W + proper gearing: 15:30-16:00 +- ### Realistic Pathways to 15:08: + + **Option 1:** Switch to gears + maintain current 214W:**~17:00 (not quite there)** + + **Option 2:** Switch to gears + increase to 245W:**~15:08 ✓** + + **Option 3:** Keep singlespeed + increase to 300W+:**~15:08 (extremely difficult, cadence issues persist)** + + **Option 4:** Gears + lose 15 lbs + 230W:**~15:08 ✓** +- ### Gearing Recommendation Based on Your Data: + + Looking at the gear comparison above with your actual 214W power output: +- **38/14 or 38/16: TOO HARD** - You'd be spinning 90-110+ rpm on easier sections (leg speed limited, wastes energy) +- **38/18: MARGINAL** - Better than 20t but still drops below 60 rpm on steep sections +- **38/20: YOUR CURRENT** - Forces 46 rpm on steepest sections = catastrophic muscular fatigue +- **38/22: BEST OPTION** - Keeps you in 60-70 rpm range on steep sections, 75-85 rpm on moderate sections + + Recommendation: Switch to 38/22 (1.73 ratio). This should save you 45-75 seconds and feel far more sustainable. You'll spin a bit faster on easy sections (85-90 rpm) but maintain viable cadence (60-65 rpm) on the steepest pitches. +- ### Realistic Pathways to 15:08 (Updated with Cog Options): + + **Option 1:** Switch to 38/22 + maintain current 214W:**~17:45-18:00 (better but not enough)** + + **Option 2:** 38/22 + increase to 245W:**~15:15 (very close!) ✓** + + **Option 3:** 38/22 + increase to 260W:**~14:50 (beats target!) ✓✓** + + **Option 4:** Full geared bike with optimal ratios:**Even better, but 38/22 gets you close** +- ### ⚡ Quick Win Strategy: + + **Next attempt: Use the 38/22 cog.** This single change will: +- ✓ Prevent the catastrophic slowdown you had at 39:00 (from 46 rpm → 60-65 rpm) +- ✓ Let you sustain power more evenly throughout the climb +- ✓ Save 45-75 seconds immediately with no fitness change +- ✓ Allow you to access more of your cardiovascular capacity (your HR showed room to push harder) + + Then focus training on raising your sustained power from 214W to 240-250W over the next 8-12 weeks, and 15:08 becomes very achievable. + + 4 \ No newline at end of file
