2026/08/05 | 22 mins.This week Coach Rob answers listener questions covering the details that trip up first-time IRONMAN athletes.
What actually goes in your special needs bags on the bike and run course?
Should you change kit in transition or race the whole day in a tri suit?
What does the final two-week taper look like after your last race simulation?
Rob also breaks down aero gains beyond clip-on bars - race wheels, tires, shaved legs - plus the essential spares and tools you need to fix problems yourself on race day, since mechanical support on course is limited.
We also hear listener race reports from a first full IRONMAN in Switzerland and a first 70.3 finish at The Lakesman.

2026/07/29 | 26 mins.In this episode:
Racing without a power meter: why Rob thinks a power meter is a "worry removal tool" rather than a cost, and how to reframe the spend over your training block. If you're going with heart rate, he covers the five variables that distort it, the time-lag that trips you up, how to set functional threshold heart rate from a 20-minute test, and the thirds-based pacing method that accounts for cardiac drift.
Training at altitude for a sea-level race: why you need two sets of zones, not one. How to find your delta between altitude and sea level, and why heart rate gives you a bridge between the two while pace never will.
Shoulder pain in the aero position: normal adaptation or warning sign? Why "I've had a bike fit" doesn't rule out a problem, why pain in the water as well changes the picture, and why regular hands-on physio work beats pushing through it.
Success story: Listener Max takes on IRONMAN Switzerland in 30°C heat with 2,200m of climbing and comes home in just over 12 hours!

2026/07/22 | 23 mins.Should busy age-groupers actually race in carbon-plated shoes? And how do you train for an IRONMAN when your job runs on four-days-on, four-days-off night shifts?
In this listener Q&A, Coach Rob Wilby answers real questions from athletes preparing for their first IRONMAN and 70.3. He covers how to structure training around shift work and disrupted sleep, why recovery has to come before more training, and how HRV tracking helps you know when to push and when to back off. He digs into whether carbon-plate race shoes are right for the paces most age-groupers actually run, why comfort and cushioning usually matter more than "free speed," and what to do when your only pool is 16 metres long. Plus a first-timer success story from Stephanie and Michael, who trained through Canadian winters and just finished IRONMAN Austria.
Topics in this episode:
Seven-day vs eight-day training cycles for shift workers
Using HRV to guide recovery (and why your feelings can lie to you)
Getting meaningful swim work done in a tiny pool
Carbon-plate vs cushioned shoes for 70.3 and full-distance IRONMAN
A first-time IRONMAN success story from IRONMAN Austria

2026/07/15 | 26 mins.Success on IRONMAN race day is as much a fuelling equation as a fitness challenge.
This episode Coach Rob Wilby works through a batch of athlete questions on carbohydrate intake, hydration, electrolytes and bottle strategy, all framed by the recent heat spells that saw IRONMAN France cancelled, Frankfurt shortened and lots of other European races affected.
In this episode:
Should carbs per hour be based on body weight? Why gut absorption matters more than size, the 1g per kilo starting point, where the ~100g/hr ceiling really sits, and the truth about those 150g pro fuelling stories.
How hard to push carbs in training. The safe way to build tolerance and how to adjust intake in the heat.
How much to drink on the bike and run. The 500–700ml/hr starting point, why sweat rates range from 300 to 1,500ml/hr, and how a sweat test plus good record-keeping in TrainingPeaks takes the guesswork out.
Refilling bottles on course. Why you don't need to at branded IRONMAN aid stations, Rob's grab-and-cool technique, and how to carry concentrated PFH and dilute on the go for non-branded races.
Separating carbs from electrolytes. The case for one concentrated carb bottle and one strong electrolyte bottle.
Rob's Almere 2008 cautionary tale. Over-biking, not peeing, going hyponatremic, and coming round in the med tent with two IVs - the race that changed how he thinks about hydration for good.
Whether it's your first IRONMAN or 70.3 or you're fine-tuning a hot-race strategy, this one will help you cross the line feeling good rather than in the med tent.
