Newcastle marathon debrief

Me: Hey brother, so I did the marathon today, didn't go as planned...

Ahh mate… that’s a tough place to be. Let’s not sugarcoat it — when you’ve put in the work and it doesn’t come together on race day, it stings.

But before we go anywhere else:

One race doesn’t define where you’re at.

And it definitely doesn’t erase the training you’ve built.

First thing — I need your data

Give me the honest rundown:

• Finish time (if you finished)

• Splits or where it started to go wrong

• Heart rate if you tracked it

• Fueling — did you stick to the plan?

• Any cramps / GI issues / blow-up point

• Weather / course factors

• Most importantly: how it felt vs what you expected

But let me say this upfront

There are only a handful of common reasons marathons go sideways:

1. Pacing slightly too aggressive early

2. Fueling/hydration not quite enough

3. Cumulative fatigue (training or life)

4. Mental tightening at the critical point (your 30km marker)

5. Race-day variables (weather, course, gut, nerves)

It’s almost always a combination — not one thing.

The key mindset right now

Don’t jump to:

“I failed” or “I’m not at that level”

Instead:

“This race gave me data.”

Because it did.

And this is important for you specifically:

You’re not a beginner guessing anymore —
you’re now in the phase where:

small execution details = big outcome swings

Also… quick check on something

You made a pretty big mental shift pre-race (ditching the hat, etc.)

That’s powerful long-term…

…but sometimes making too many changes at once before a race can subtly add pressure.

We’ll unpack that properly once I see what happened.

Right now

Take a breath.

You:

• showed up

• put yourself on the line

• chased something meaningful

That already separates you from most.

Send me the details and we’ll break it down properly — not emotionally, but like a post-race debrief from a coach.

We’ll figure out:

• what actually happened

• what to fix

• and how this sets up your next jump

I’ve got you.

Me: total time 3:30:11, I did the first 30km in 2:22:57 and then popped around the 33km mark, cramped frequently and struggled to the end. nailed the gel plan, maybe hydration was a little low, avg heart rate 157bpm, avg cadence 172spm, avg temp 24 degrees, total ascent 454m so not flat

Alright… this is actually a really clean debrief, and I’m going to be straight with you:

This was not a “bad race” — this was a predictable outcome from a few specific variables stacking up.

And the good news?

None of them are fundamental limitations.

🧠 Let’s break it down properly

Your numbers:

• 30km: 2:22:57 → ~4:46/km

• Finish: 3:30:11

• Blow-up: ~33km

• HR: 157 avg

• Cadence: 172 (solid)

• Temp: 24°C ☀️

• Elevation: 454m ⛰️ (this is BIG)

🚨 The headline (this is the truth)

You ran a flat-course pace on a non-flat course, in warm conditions

…and your body called it at 33km.

🧩 What actually caused the cramping

This is important — cramps weren’t random.

They were the result of 3 combined stressors:

1. Course elevation (quiet killer)

454m of elevation is not nothing.

That means:

• More muscular load (especially calves/quads)

• More eccentric damage on downhills

• Higher neuromuscular fatigue

👉 Even if your pace looks controlled, your legs are working harder than the numbers suggest

2. Temperature (24°C is significant)

This alone changes the race.

At that temp:

• HR drifts higher

• Sweat rate increases

• Electrolyte loss increases

• Perceived effort climbs

👉 A “safe pace” in cool weather becomes too aggressive in heat

3. Hydration (your own flag)

You said:

“maybe hydration was a little low”

I’d upgrade that to:

Hydration was likely a key contributor

Because:

• Heat + elevation + duration

• → higher sweat rate

• → reduced plasma volume

• → earlier neuromuscular fatigue

• → cramping trigger

🧠 What about pacing?

Here’s the subtle part.

Your 30km split:

2:22:57 (~4:46/km)

That’s actually reasonable…

👉 IF:

• flat course

• cool conditions

But in your conditions?

It was probably 5–10 sec/km too quick early

That’s all it takes.

💥 Why it hit at 33km (not 30km)

This is interesting — and important.

In Auckland:

• You popped at ~30km (fuel/conditioning limit)

Here:

• You held longer → 33km

👉 That means:

You’ve improved

But:

• the added stress (heat + hills + hydration)

• delayed the breakdown slightly… then tipped you over

🧠 What you actually proved today

This is the part you need to hear:

You are very close to 3:15–3:20 fitness

Because:

• You held solid pace for 30km

• HR wasn’t outrageous

• Fueling was nailed

• Form (cadence) held

You didn’t blow up because you’re not fit enough.

You blew up because:

the conditions required a different strategy

🔧 What to fix (this is gold for next race)

1. Adjust for conditions

In 24°C + elevation:

👉 Start ~5–10 sec/km slower

That alone likely gets you to:

~3:20–3:25 finish instead of 3:30+

2. Hydration becomes a priority

Not optional.

Next time:

• Small sip at every station

• Consider electrolytes (if available)

• Don’t rely on thirst

3. Respect elevation

Think:

“Effort, not pace”

On hills:

• Let pace drop slightly

• Keep effort smooth

4. Cramp prevention = relaxation

Even late race:

• loosen shoulders

• quick cadence

• don’t “push harder” when fatigued

🧠 Mental piece (important for you)

You didn’t “fail at 30km again”

You:

extended your limit under harder conditions

That’s progress.

🏁 The honest summary

If this race was:

• 12–16°C

• flat course

With the same execution?

You likely run 3:18–3:22

No question.

Final thought, brother

This wasn’t a collapse.

It was:

a miscalculation of environment vs effort

That’s a much easier fix than “not being good enough.”

If you want, next step we can do:

• build your next race plan adjusted for conditions

• or map a training tweak to bulletproof that 30–42km section

You’re close. Like properly close.
