Twigg could be world champion by the end of next weekend. She has always been ambitious but even a silver or bronze in Slovenia will mean her Olympic dream of London gold remains in firm focus.
Twigg has been the youngest genuine contender in the field for some time against formidable rivals like double Olympic and six-time world champion Ekaterina Karsten of Belarus and 2010 world champion Frida Svensson.
The catalyst for change may have come in Twigg's World Cup win into a headwind down the Rotsee in Lucerne last month. She led through each of the 500m trigger points over the 2km, signalling she now has the ability to control races. Previously she was grateful to scrap to the end - as when she clung on for bronze at Lake Karapiro in November.
"We're making baby steps, putting it all together," Twigg says referring to her and coaching guru Dick Tonks. "It was a big confidence boost taking those scalps at Lucerne. It was unusual and I was surprised to be in that position. Putting fear into some of the older girls is reassuring. Finally managing to beat Karsten regularly is a step forward.
"If you look at last year's world championships when I had to come from behind, it's a better position to be in."
Tonks, famous for his reticence, is relatively confident: "Emma has the pedigree. She has had a good, steady career. She ran out of steam 100m from the line last year but was still challenging in the last 500m.
"There's a certain advantage being in front all the way. It takes an exceptional athlete to keep their composure coming from behind. It's all about being in front, relaxing and controlling the race."
