Know the course

These are the spots that statistically cause wrong turns / lost time:

• Early race congestion: first 5–10 minutes (swim exit → T1, start of bike, start of run). You’re distracted + following bodies instead of signs.
• Course splits: where distances diverge (Sprint vs Olympic / Relay vs Individual).
• Multiple-lap formats: the “Did I do 2 or 3 laps?” problem—especially on run loops.
• Turnarounds U-turn & cones: athletes miss the cone, turn early, or continue straight.
• Re-entry points: coming back into transition or finish chute—can be confusing if there’s also a public area.

 

Action: When you look at the map, identify every split, every lap point, every turnaround, and each transition entry/exit.

When you check maps, don’t just “understand the shape.” Extract race-critical data:

Bike

• Total distance + lap count
• Direction of travel (clockwise/counterclockwise)
• Key turns: “hard right after roundabout” type notes
• Aid stations / bottle drops (if any)
• Surface hazards: potholes, rail tracks, cobbles, gravel shoulders
• Wind exposure zones (open coastline, bridge, long straight)

 

Run

• Distance + lap count
• Out-and-back vs loop
• Aid station spacing (practically: where you can drink)
• Shade/exposure (heat management)
• Narrow points (where passing is hard)

 

Transitions

• Exactly where you enter and exit
• “Flow”: Swim exit → T1 rack → mount line / Run out

“Mount / dismount line” location (many penalties happen here)

That sentence is important: marshals are primarily for safety and control, not personal navigation.

• They may be placed at dangerous intersections, not every turn.
• They may be dealing with traffic/public, not watching each athlete’s decision.
• They might not know your distance category.

 

Implication: If you miss a sign, “following a marshal’s arm wave” is not a guarantee you’re right

It’s not just “I don’t get the map.” It includes:

• A junction where two directions look valid
• Any place where cones could be moved by wind / public
• A section that relies on temporary signage
• Confusion about laps or where to turn around
• Transition entry/exit that isn’t obvious from the venue layout

 

Best practice questions to organiser (very specific):

• “At km X, do we take the first or second right after the roundabout?”
• “Where exactly is the turnaround cone for the run?”
• “Is the bike course fully closed to traffic or partially open?”

Use these rules to avoid panic decisions:

• If you don’t see course tape/signage for ~5–10 seconds, slow slightly and scan—don’t sprint into a wrong turn.
• Don’t rely on one athlete. If three people go left, they can all be wrong.
• At every major junction, look for confirmation: arrow sign + tape + cones.

 

If you go wrong: safest approach is to turn back immediately when safe (not across live traffic) and rejoin at the last known correct point

Knowing the course isn’t just “nice to have.”

• Time loss: wrong turn + correction is often 30 seconds to several minutes
• Physiological cost: sudden braking/accelerating spikes effort and HR
• Penalty / DQ risk: missing a turnaround, incorrect lap count, wrong mount/dismount behavior

• Save the course map images offline (phone gallery) + note key turns
• If available, load GPX into your watch/bike computer (even if you don’t “navigate” with it)
• Walk/ride the critical 200–500m segments if you can:
  • swim exit → T1
  • T1 → mount line
  • dismount line → T2
  • run exit and finish chute approach
