Race summary

This was a 9:12:22 race decided on the bike, specifically in the first 108 km.

You averaged 255W normalized across the opening three segments when the top of your target range was 247W, then produced only 198W in the final 36 km. That is not a nutrition problem or a cramp; that is the cost of spending what you did not have. The run confirmed it: cardiac suppression was present by km 21, with HR dropping from 154 to 148 bpm as pace fell from 4:44 to 5:07/km. The course turned through the wind: 60 km into it, 60 km back with it, netting 0.2 m/s across 180 km, so where it fell matters more than how much of it there was. The hardest stretch on the nose came at 75–90 km, through the middle hours, and that is exactly where your power held. From 120 km to the finish you had the wind behind you, and that is the stretch where normalized power fell to 198W. The conditions cannot carry that. Officially, your T1 of 4:15 sat 38 s over the M40-44 median of 3:37, and 2 athletes in your age group finished within that margin.

The day you raced in

The day warmed steadily under you, from 20.2C at the start to 27.1C at its warmest during the bike, a 6.9C climb across the race. The wind held steady at about 21 km/h (moderate) from start to finish and stayed out of the WSW. The day asked most of you through the wind: 60 of the 180 km you covered were spent pointing into a moderate wind, while the heat load stayed at warm. The hardest stretch anywhere in the race was 75 to 90 km on the bike, at 6.1 m/s on the nose. Where that actually landed is on the leg page.

Your watch recorded 3,840 m in 1:02:29, an average of 1:38 per 100 m. Your first 500 m was 6.1% quicker than the pace you settled into, at 1:32 per 100 m against 1:38. Your last two full laps were 3.1% slower than the laps before them, at 1:40 per 100 m against 1:37.

Open-water GPS is approximate: your watch loses its signal every time it goes underwater, so treat the swim distance and pace here as an indication, not a measurement.

Times and distances are what your watch recorded, not the official split. The last bar runs on past the swim exit, so it is drawn hatched and left out of any comparison.

Your official T1 was 4:15. The M40-44 median was 3:37, so 38 s was on the table against it.

2 athletes in your age group finished within that margin.

Against the quickest tenth of your age group (2:41) the gap was 1:34, and 4 athletes in your age group finished within it.

Fastest in your age group: 2:30. A single time, shown for scale, never the target.

Bike · 180 km

Moderate wind averaging 6.0 m/s (22 km/h) from the WSW. The course turned through it: 33.3% of the distance into the wind and 33.3% with it, netting 0.2 m/s along the direction of travel. On balance the wind neither gave nor took much. The hardest stretch was 75-90 km at 6.1 m/s on the nose. Air temperature averaged 24.0C (feels like 26C) at 50% humidity. Warm enough to cost a few beats per minute of heart-rate drift at the same effort, though not on its own enough to account for a large fade.

Your intensity factor of 0.725 met expectations for sub-5-hour cycling, but the progression across segments reveals a consistently front-loaded effort. Power dropped from 262W NP in the opening 36 km to 198W NP in the final 36 km, a 24% decline. Heart rate followed the same pattern, peaking at 149 bpm through km 36–72 then falling progressively to 141 bpm, the signature of cardiac output suppression by the final third. The wind was on the nose through the middle of that decline and behind you for the end of it, so it is not what moved the numbers.

Your run HR averaged 154 bpm across the first 21 km and dropped to 148–151 bpm from km 20 onward — a signature of cardiac suppression, not pacing discipline. The pace ceiling was set in the first 5 km, not in the back half where most athletes remember struggling. You set out to run 4:40/km and opened at 4:23, 17 s/km quicker than that. Conditions on the run were unremarkable and did not shape this.

What to take into your next race

What you did well

You rode the bike without surges: how variable your power was came out at 1.01, under the 1.05 that marks a steady ride. Riding without surges keeps what the bike costs to what its average power shows. Through the 15 km on the nose from km 75, into 6.1 m/s, you sat at 248W with your heart rate at 148, four beats above where you opened.

What to adjust

Hold the first half of the marathon at 138 to 148 bpm. That keeps the first half at an effort the second half can match. Read your average heart rate at halfway, inside that range. It stays put in any conditions; heat shows up in the pace you can hold under it, not in this number.

Your intensity factor sits within 0.020 of the top of the target band for this distance. These findings assume the entered FTP is accurate and current. If your FTP has not been tested in six or more weeks, the bike analysis may understate your actual effort level.
