Panic at the Mass Start: A Five-Week Open-Water Reset
An athlete you coach is a 34-year-old female with a pool 1500 m time of 25:00 (1:40/100 m) and an open-water race in 5 weeks. Last year at the same event she panicked at the mass start, hyperventilated, switched to breaststroke, and finished in 34 minutes. Water temperature is forecast at 18°C, so a wetsuit will be allowed. She owns a well-fitted wetsuit but has worn it only twice, both in a pool. She has no history of anxiety disorder, swims two to three times weekly, and completed one other open-water triathlon two years ago without incident. She wants to know whether she should start at the front to avoid traffic, whether to use the wetsuit, and what to do in the final 5 weeks. She is training 9 hours/week and is 8 weeks out from her main 70.3.
1. What is the most likely explanation for the 34-minute swim, and what factors will you assess?
Read the worked answer
The 9-minute gap is too large to be explained by fitness alone. Her pool time shows she can swim; the race pattern-panic at the mass start, hyperventilation, breaststroke-points to a start-related anxiety and cold-shock response. At 18°C, the gasp reflex, increased heart rate and chest tightness are normal, and an unfamiliar wetsuit adds chest compression and restricts breathing. The mass start adds contact, noise and sighting demands. She has worn the wetsuit only twice in a pool, so she has not practised the specific skills under race conditions. Assess: whether the wetsuit fits and allows full breathing; her response to cold-water face immersion; her ability to sight and navigate; her start-position plan; and her breathing pattern under contact. Do not frame this as a character flaw. The intervention is exposure and skill rehearsal, not simply 'swim more'.
2. Design the 5-week swim exposure progression.

Keep two to three swims per week, but change the content. Week 1: two pool sessions in the wetsuit, 400-600 m total, easy, with deliberate exhale into the water and 25 m head-up sighting, if pool rules allow the wetsuit. Week 2: one open-water session, 20-25 minutes: enter gradually, splash the face, swim 4x200 m easy with sighting every 8 strokes. Week 3: open-water session with three or four teammates, simulate a mass start from a wide position, practise contact and reset to breaststroke, then resume. Week 4: race-specific 800-1000 m in the wetsuit at goal effort, plus a cold-water acclimation dip. Week 5: taper; one short open-water activation of 10-15 minutes two days before, and a 10-minute warm-up on race morning. Include a pool session with a sleeveless wetsuit option if chest restriction persists. Log anxiety 0-10 before and after each exposure; the goal is familiarity, not exhaustion.
3. What start and in-race reset strategy do you teach her?
Read the worked answer
Start wide and toward the back of the first line, not at the front. The front is for swimmers who want contact and have practised it; her goal is clean water and controlled breathing. Enter the water 10-15 minutes before the start, immerse her face, exhale slowly, and do 5-10 minutes of easy swimming to reduce cold shock. In the first 200 m, swim at 80-85% effort, count strokes, and sight every 8-10 strokes. If panic starts, roll onto her back or breaststroke, breathe out fully, look at a fixed point, and reset before returning to freestyle. Give her a short cue: 'exhale, lengthen, sight.' Use the wetsuit if allowed and practised, because buoyancy helps, but switch to sleeveless if breathing is restricted. Plan the first buoy approach: go wide, turn wide, and avoid the washing machine. Rehearse this in week 3.
