Layering question

Hey all, I’m wondering if any of you could tell me what you would where for a short Duathlon with the temperature areound 65. I’m leaning towards a tri singlet, long sleeve under-armor and some cycling shorts. Thanks for the help.

Personally, that would be too much for me, especially on the runs. At the most I would wear a tri singlet and tri shorts, possibly with arm warmers on the bike (roll down on the run or toss for the 2nd run.

Tri singlet and tri shorts. You’d get way too hot with more layers, or even just by covering your arms & legs.
