Who's Behind It?

The dream of two female triathletes based in London, Threo has quickly become the most talked about name in UK triathlon since its creation in 2014.

How did it come about? Laura and Rhian, the two founders, recognised the shortage of really well designed triathlon kit for women. At the same time they recognised the nonsense that is the cycling/triathlon 'divide'.

So they set out to design and manufacture kit that looked beautiful and distinctive without being garish, that fits real women perfectly, and that can be used by triathletes, cyclists, runners... in fact, by anyone who loves physical activity! They've worked miracles in creating a top notch brand whilst juggling pregnancy, motherhood and maternity leave, and the products are simply some of the classiest around.
