Top 10 Triathlon Race Tips for Your First or Fastest Race

Finishing a triathlon requires you to overcome some non-trivial logistics; a duathlon is far more straightforward. Thinking about logistics can be daunting for your first race, and all the worries just add to the stress and can spoil your enjoyment and performance on the day.

Here are some of the tips you’ll read about in the standard Top 10 Triathlon Tips posts, but I’ve added in a few more unusual ones as well to give you some more things to think about.

Well in advance

• Get your bike serviced a few weeks beforehand, or at least enough time to give it a good test at race pace and check your mechanic tightened all the bolts and indexed the gears in the real world, not on their bike stand.
• Same with race day shoes. You will likely be using a ‘special pair’. At least wear them for 10 miles of training or tapering runs
• Get the elastic laces in your special shoes now. When you do transition practice leading up to race day, you want those special shoes to be exactly the same as on race day, with the right tension.
• Same with your goggles. You want to swim in your race-day goggles a couple of times. If they are an old pair, you want to be certain they are clean and will not leak.
• Buy all your usual nutrition brands for race day. Get them in your house a week beforehand. Don’t buy them the day before in your local shop.
• Do all the race admin now. Confirm that place. Send timings to friends. Check your triathlon national membership, whatever you need to do. Do it now.
• Have you got all your unusual accessories, like a specially coloured towel to mark the transition, earplugs, elastic bands, emergency bike tools, and a puncture repair kit? Start to accumulate that stash now in a box.

A day or so before

• Finalise accumulating your race-day bits, pieces and spares. E.g. put that tri belt and your socks into your race box
• Charge all your electrical gadgets – Di2, power meter, chest strap, Stryd, bike computer, watch, all of it. Pack spare chargers for your PM and Di2, as you can lose charge during transportation
• Load the race route if needed. Make sure the route includes elevation profiles if that is important to you.
• Check the weather and adjust for likely rain, wind and sea conditions. As race-day temperatures rise above 16 degrees Celsius, your running performance will be progressively affected. Adjust your plan as needed by consulting online calculators that will indicate the slower pace to run at.

• If you plan to rely on a watch’s multisport mode, ensure it’s configured properly, with transition, autolaps, and alerts enabled or disabled as you prefer. Verify that race day mode works with a dry run.
• Practising multiple live bike-run transitions is also a very good idea. Start bike+run slow. Finish. Reset, and start again faster. Stop only when it goes smoothly.
• Final chain lube, brake check and slow puncture check.
• The night before. Look at your box full of stuff. Go through the race mentally or even simulate using each piece of kit and when you will use it. You’ll find you forgot something. Repeat.

A fast race in a non-drafting event is always an evenly paced one. Understand exactly what your paces and speeds are. The swim doesn’t matter so much, just go flat out. Really understand what your bike pace should be; you almost certainly don’t want to base a long race on your FTP, as that likely won’t reflect how you can handle > 1-hour pacing unless you are well-trained. Look at the actual power durations you’ve achieved in real life, and then you’ll likely target slightly lower than those (you should have done this earlier).

On the day

Definitely get there early; in some races, that will mean you can choose a good transition spot at the right end of the racks.

Swim Preparation

• You’ve already chosen the right goggle lens for the level of sunlight and time of day, and you will know whether you are a two-cap person or a one-cap person.
• If you are not a contender and not a great swimmer, don’t go anywhere near the front of a water start. 5 seconds wasted here could mean a few saved bruises or dislodged goggles later.

Race Execution

• You have a realistic plan. Follow it.
• Warmup. It’s more important to warm up thoroughly for shorter, faster races.
• You have a nutrition plan. Follow it. If you are a finisher rather than aiming for a podium, 3 gels an hour in an Ironman may well cause you GI issues. You’ve already tested your nutrition plan, so you know what to do.

Take Out

The keys to successful triathlon logistics are planning and rehearsing.

Rehearse your transitions the week before. Go through all the motions of changing every piece of race-day gear at home in the dry. Physically jog transition routes on race day.

Planning helps you avoid forgetting things. Rehearsing helps you remember what to do with them and when.
