T2 Setup Guide: Bike-to-Run Transition
Rack the bike, lace up, and run out with jelly legs under control
T2 is usually faster than T1 — fewer items, no wetsuit — but it's where your legs betray you. Planning for tired quads and a foggy brain is the real work.
What's on the Towel for T2
Essentials
- • Running shoes with elastic laces
- • Visor or running cap
- • Race belt (spin the number to the front)
- • Gels or fuel for the run in pockets
Optional but useful
- • Fresh socks (only if you can pull them onto wet feet)
- • Sunscreen stick (long races)
- • Handheld flask (70.3+)
- • Anti-chafe balm
Step-by-Step T2 Sequence
1. Unclip early, feet on top of shoes
About 200m before the dismount line, unclip and ride with your feet on top of your cycling shoes. This avoids hopping off the bike in clip-clop mode and cuts 10–20 seconds.
2. Dismount before the line
Swing a leg over and run barefoot (or in shoes, depending on your practice). Dismount past the line is a penalty.
3. Rack the bike, then remove helmet
Hang the bike on your assigned rack. Only after it's racked can you undo your helmet strap. Helmet off before you leave transition is another common DQ.
4. Shoes on — elastic laces are gold
Step into running shoes. Elastic laces turn a 20-second knot session into a 2-second slip-on. Every triathlete should own a pair.
5. Visor, belt, go
Visor on (flips sweat forward, shades the eyes), race belt rotated so the number is on your front, and out through the run exit.
Time Targets by Distance
| Distance | Beginner T2 | Age-Group Goal | Front-of-Pack |
|---|---|---|---|
| Sprint | 1:30 - 3:00 | 1:00 - 1:30 | Under 0:45 |
| Olympic | 2:00 - 3:30 | 1:15 - 2:00 | Under 1:00 |
| Half Ironman | 3:00 - 5:00 | 2:00 - 3:00 | Under 1:30 |
| Full Ironman | 5:00 - 8:00 | 3:00 - 5:00 | Under 2:30 |
Managing Jelly Legs Off the Bike
Spin out the last kilometre
Drop to an easy gear and spin at 95–100 rpm for the final minute of the bike. This loosens the legs before you start running.
Start slower than you feel like
The first 400m will feel strangely fast and strangely hard at the same time. Dial it back for the first kilometre — your legs catch up.
Practice with bricks
A weekly brick workout is the single best way to normalise the sensation. Even 10 minutes of running after a bike ride rewires your nervous system.
Common T2 Mistakes
Removing the helmet before racking
Penalty or DQ depending on the race. Rack first, unbuckle second.
Tying shoe laces
Elastic laces eliminate an entire category of mistake. Ten dollars, permanent fix.
Forgetting the race belt flip
Number on back during the bike, on front for the run. Officials at the start of the run course check.
