Which transition rules do I enforce, and what is the penalty?

Question

Accepted Answer

Key rules under World Triathlon rule 7.1: Rule What to check Racking Own spot only. T1: upright, saddle hooked over the bar, front wheel pointing into the lane (the Head Referee may allow exceptions). T2: either way, with handlebar sides, brake levers or saddle within 0.5 m of the rack number, not blocking anyone Kit position Equipment for later must be within 0.5 m of the bin (or of the rack number if there's no bin). At the end of the last transition, all kit goes in the bin, apart from bike shoes left on the pedals and bike items (not helmet or glasses) that were on the bike from T1 Discarding Intentionally dropping items between the swim exit and transition earns a penalty Mount and dismount Mount after the mount line, with one complete foot on the ground beyond it. Dismount before the dismount line the same way. Cycling out of transition instead of mounting at the line, or making no attempt to dismount and riding into transition, means disqualification Pushing the bike By hand only, inside transition Helmet Strap unfastened while the athlete is in transition finishing the first leg. Fastened from lifting the bike off the rack until it is re-racked and let go. The lock may not be opened or closed in between Impeding Interference that stops another athlete continuing means disqualification. An athlete may move misplaced kit that is in their way Flow zones Athletes may not stop in them Wetsuit Only fully removed at the athlete's spot or a designated area, with the torso covered. Nudity or indecent exposure is forbidden Lost kit Shoes or kit dropped while mounting or dismounting are collected by officials, with no penalty Where age-groupers serve transition penalties (rule 3.3 b): an infringement in T1 or T2 is served as a time penalty on the spot. The run penalty box board, with letter codes such as D (dismount line), M (mount line) and E (equipment outside bin), is used for elite and para categories.
