IRONMAN Bike Pace Guide. How to ride strongly and then run faster than ever.
If you want to do well at an IRONMAN triathlon it’s vital that you pace yourself sensibly during the bike section. Once your legs get too sore from riding hard you have almost no chance of running well afterwards. There is no going back from this point – the run section will feel like purgatory.
Therefore your goal is to ride at the fastest IRONMAN pace that still enables you to run well afterwards. In other words, don’t focus too much on being a hero and posting a super-fast bike split. If you ride too fast, the chances are you’ll undo all your hard work by not being able to run properly afterwards.
Riding at the right intensity takes discipline and courage especially when other people are overtaking you, but it really works. At around the 80-mile point, you’ll notice people starting to drop off while you continue to ride strongly, overtaking people as you go.
You’ll also find that pacing yourself sensibly helps you to digest your energy drinks and snacks far easier, which helps you maintain your energy levels going into the run.
Intelligent pacing leads to faster, more consistent IRONMAN results. And yet hardly anyone gets it right. I just hope this feature helps you make the right pacing choices at your next IRONMAN.
Use our Triathlon Race Pace Calculator to help you establish your optimal race-day IRONMAN bike intensity, so that you ride the best time possible while still saving your legs for the run.
Finally, remember that it’s crucial to base your IRONMAN race pace on recent training and race data, such as an FTP and HR Threshold test. Don’t be over-optimistic about your race pace or simply guess it. This is the path to failure.
