Tuhia he tomokanga mo tenei whitianga - I arotahi a Thomas ki te pahikara ara mo te tau 2012, i whakataetae i nga Taakaro Orimipia o te Raumati i Ranana. Na reira, ko te Giro d'Italia tana kaupapa tuatahi mo te whakataetae ara, i mua i tana huri i tana aro ki te ara. I te marama o Poutu-te-rangi, i eke a Thomas i Paris ki Nice, i reira i awhina ai ia i a Bradley Wiggins ki te wikitoria katoa. I te 4 o Paenga-whāwhā ko Thomas he mema o te kapa whaiwhai o Ingarangi i toa i te koura i te UCI Track Cycling World Championships
i Melbourne, me te rekoata ao hou o te 3: 53.295 hēkona. I mahi tahi hoki ia me Ben Swift ki te tango i te mētara hiriwa i te madison. Katahi ka hoki a Thomas ki te huarahi, ka wikitoria i te kupu whakataki o te Tour de Romandie.
