Middle Distance Cheat Sheet

The key takeaways for beginners – the first 30 bike minutes, doubled fuelling and race pace instead of your old Olympic-distance feel.

Gear that's actually worth it

Item	Priority	Tip
Aero clip-ons	High	No time-trial bike needed – a trained position on clip-on bars already makes a real difference over 90 km.
Nutrition system	High	One bottle isn't enough: fit bottles and gels for 60–90 g of carbs per hour onto the bike.
Race shoes	Medium	Test them in a brick after a long ride – kilometre 2 feels very different after 90 km on the bike.

Placing the middle distance

Right in the middle: 1.9 km swim, 90 km bike, 21.1 km run – twice as long as Olympic distance, half as long as the full distance.
Tight time limits: 1:10 h for the swim, 5:30 h for swim plus bike, 8:30 h overall – do the maths beforehand.
Drafting only in the water: Drafting while swimming is explicitly allowed and saves energy – on the bike, solo riding applies again immediately.

The 3 golden pacing rules

Factor 1: The first 30 to 45 bike minutes decide it

Concept: Most middle-distance races are lost right here, not in the run afterwards – adrenaline after the swim exit tempts you to overpace. Tip: Set your target zone in advance: 70–78% of FTP as normalized power, up to 85% for strong runners – and deliberately hold back the first 20 minutes.

Factor 2: Double the fuelling, don't just stretch it

Concept: What was enough at Olympic distance falls short over 90 km – 60–90 g of carbs per hour is non-negotiable here. Tip: Start eating actively from minute 15–20 on the bike, not once hunger hits – switch to easier-to-digest gels and drinks on the run.

Factor 3: Start at marathon pace, not half-marathon pace

Concept: The most common cause of a blow-up is starting the run too fast after 90 km on the bike. Tip: Plan a deliberate 500–800 m reset phase after dismounting, then start closer to marathon than half-marathon pace.

Race tactics by the numbers

Topic	In short
Talk test	Without a power meter: as long as you can speak full sentences, your bike pace is sustainable.
Reserve for the finish	Deliberately hold back 5–10% of capacity for the last kilometres instead of burning it all on the bike.
Heat factor	Every degree above 17°C costs 0.2–1.1% run pace – cool actively at every station, not just drink.

The biggest mistakes moving up from Olympic

Recalibrate your pacing: What feels like good pace at Olympic distance is often already too hard at middle distance.
Fuelling becomes non-negotiable: 60–90 g of carbs per hour from early in the race, instead of one gel just before the finish.
Estimate your goal time realistically: Don't extrapolate linearly from your Olympic-distance time – build in a safety margin for your first attempt.
Train genuinely long sessions: Build up to 90–120 minute runs and 3+ hour rides over several months – there's no shortcut here.

Pro tip: Your middle-distance time is not double your Olympic-distance time. Build in an honest safety margin, deliberately hold the first 20 bike minutes too slow – and let the finish line surprise you, in a good way.
