Should you ride the bike course in race week? How do you overtake within the 25-second drafting rule without spiking your power? And what’s the fix for hyperventilating at the start of an IRONMAN swim?
This week Coach Rob Wilby answers questions from three listeners who’ve just raced, or are building towards, their first 70.3 and IRONMAN:

Struggling with stomach problems on the IRONMAN run? This week Coach Rob Wilby answers a listener question from Tracy, who finished IRONMAN Kalmar but had stomach trouble on the run and wants to fuel with real food instead of gels.
Rob explains why the carbs may not be the culprit. Riding too hard on the bike can shut down blood supply to your gut, and he shares the bike TSS numbers to stay under. He also covers real-food options that work during an IRONMAN, such as bars, chews, bananas and rice pudding, and why you should practise your race-day fuelling in training.
Then it’s a quick-fire round on the questions first-time IRONMAN athletes ask most:

Feeling flat during your taper? Worried you've never ridden the full 56 miles before your first 70.3?
Coach Rob answers listener questions on why tapering feels rubbish (and why you'll feel so much better by race day), and why you'll ride faster on race day than in training.
He also covers whether you need a TT bike for Ironman courses like Austria (spoiler: there are probably more impactful upgrades to make first), how to train for the swim in a lake, and how fit you need to be a year out from IRONMAN.
Plus athlete success stories from Ironman Wales and Leeds.

This week Coach Rob tackles a question from a first-time IRONMAN athlete juggling training with a full-time job:
"how do you structure your training year, and how many weeks out should IRONMAN-specific training actually start?"
Rob breaks down the winter base-building phase vs. the ~20-week specific build, how to shift focus from indoor FTP work to outdoor endurance riding as the days lengthen, and how to set a realistic finish-time goal from your half-IRONMAN pace.
Then it's onto three brilliant IRONMAN Leeds success stories — including a negative-split marathon PB, a FTP transformation, and a top-25% finish off just eight weeks of training. Plus a preview of IRONMAN Wales and the 70.3 World Championships in Nice.

Most IRONMAN disasters aren't down to a lack of fitness, they're mistakes made in the weeks before race day that felt completely logical at the time.
This week Coach Rob breaks down the five most common reasons a first IRONMAN goes wrong: riding the bike too hard, under-fuelling on the bike, cramping from poor electrolyte planning, walking the back half of the marathon, and panicking in the open water.
Each one is avoidable with the right preparation, and Rob gives you the fix for all five.
If you're planning a 70.3 or IRONMAN in 2027 and you don't want your big day undone by something you could've sorted in training, this one's for you.

In this episode:
Power data fields on your Garmin or Wahoo: why the default power reading is useless, and the four numbers Rob wants on your screen instead...
How to get an accurate outdoor FTP number...
Listener question: with two kids under seven and a 9-to-5, midweek sessions don't start until 8pm. Is there a caffeine substitute to get going without wrecking sleep?
Listener question: after a car accident and a rebuilt shoulder, breaststroke is the only stroke available. Can you race a 70.3 or IRONMAN breaststroke? Rob talks wetsuit fit, swimming wide of the buoys, and the harder work of setting realistic new goals when you've raced Kona
