What No One Tells You About Your First Triathlon (Women)

Here's what nobody tells you: tri suits are worn with nothing underneath. No underwear, no sports bra (most tri suits have a built-in shelf bra). This feels weird the first time, but it's designed this way for a reason — extra layers cause chafing over hours of racing and slow your transitions.

If you're not comfortable with a one-piece tri suit, a two-piece version gives you the same performance benefits with more flexibility. Try your tri suit in training at least 3 times before race day. Check that the chamois (bike pad) is comfortable on the bike and doesn't bunch when running.

Chafing happens where skin meets skin or fabric meets skin — inner thighs, sports bra line (if you wear one), neck from wetsuit, under arms, and between toes. For races over an hour, it's almost guaranteed somewhere.

Apply Body Glide or Squirrel's Nut Butter to all high-friction areas before the race. Be generous. Reapply during transitions if needed. This is the single most practical piece of advice in this article — more important than any training tip.

Let's talk about it because nobody else will. Portable toilets are available at the race venue but lines can be 15–20 minutes before the start. Plan to use them 45–60 minutes before your wave.

During the race: for Sprint distance, you probably won't need to stop. For Olympic and longer, aid stations usually have portable toilets. Some athletes (honestly, many) pee while swimming or on the bike — this is common and not as taboo as you'd think. But no one will judge you for stopping at a toilet either.

Period management: if your race falls during your period, a menstrual cup or disc works well under a tri suit. Tampons are fine too. Test your solution in training. Hormone-based options to skip your period for race day are worth discussing with your doctor if it's a major concern.

Triathlon attracts all body types. You'll see lean, muscular bodies at the start line, and you'll also see bodies of every shape and size. The beauty of triathlon is that it rewards consistency and grit over genetics.

If you feel self-conscious in a tri suit, know this: everyone is far too focused on their own race to notice what you look like. And the community is overwhelmingly supportive — you'll get cheered by strangers, encouraged by competitors, and celebrated at the finish line regardless of your time or appearance.

Focus on what your body can do, not what it looks like. You're about to swim, bike, and run in a single event. That's extraordinary.

Swim caps are provided at most races (color-coded by wave). Put your hair in a low bun or braids before putting on the cap. High ponytails create goggle seal issues.

For the bike and run, have a plan for your hair. A low ponytail or braid under a visor works well. Avoid anything that will bounce or create drag. Bobby pins can be uncomfortable under a helmet, so test your setup in training.

Sunscreen: apply waterproof SPF 50 before the race. You'll be outside for hours. Reapply during T1 if your race is longer than 2 hours.

Your first triathlon will likely include moments of: excitement, terror, pride, frustration (transitions are awkward), exhaustion, and overwhelming joy at the finish line. This is all normal.

Many women cry at the finish line — happy tears. The sense of accomplishment is profound, especially if you've doubted yourself along the way. Embrace every emotion and take a moment at the finish to appreciate what you just did.

After the race, you might feel an emotional dip. The goal you've been working toward is done. Start thinking about what's next — a longer distance, a faster time, or just another race to enjoy the experience again.

Do at least one brick session (bike + run back-to-back) and one open water swim before the race. These two sessions remove more race-day uncertainty than any other training.

Drive or walk the transition area the day before. Know where the swim exit is, where your bike is racked, and where the run course starts. Familiarity reduces anxiety enormously.

Connect with other women doing the race. Facebook groups, local tri clubs, and women-specific triathlon communities are incredibly welcoming and full of people who've been exactly where you are.
