The Polish rider attacked a reduced pack on the final time up the Orino climb finishing 23 seconds clear of Chantal Blaak (Boels-Dolmans) and Marianne Vos (WaowDeals) at the finish in Cittiglio, Italy.
“My victory today was due to an amazing team,” Niewiadoma said “From the start it was raining and the conditions were tough.
"The girls did an incredible job attacking and making the race hard for all of our competitors while I could save my energy and prepare myself mentally and physically for the last final attack."
#TrBinda winner @KNiewiadoma pays tribute to her team @WMNcycling and says she took inspiration from @vincenzonibali victory @milansanremo yesterday. “Attack and never look back” #MilanoSanremo pic.twitter.com/OOPafPFSgd — Voxwomen (@Voxwomen) March 18, 2018
Niewiadoma said she couldn't help but be motivated by Vincenzo Nibali’s Milan San Remo victory.
“I was inspired by his attack and I wanted to push hard until the finish line and never look back.
"It’s amazing that we were able to put our team plan into practice and to win the race, I’m super super happy for this. I just want to go see my teammates now and give them a big hug!”
Australian Amanda Spratt (Mitchelton-Scott) finished fourth, her compatriot and teammate Lucy Kennedy coming home ninth.
"I am happy with the performance today," Spratt said. "I felt strong during the race and good on the climbs as well. Even though I had a little injury trouble between Strade Bianche and this race, I still feel like the shape is coming along very well so today gives me a lot of confidence."
"It’s been a long time since I’ve had a sprint at the end, so coming fourth in that company is a result that I’m proud of."
The race lit up in the final three circuits when Ane Santesteban (Ale-Cipollini), Elinor Barker (Wiggle-High5) and Alena Amialiusik (Canyon SRAM) attacked atop the Orino, with 45 kilometres remaining of the total 131 kilometres.
While Barker lost contact, two more riders bridged to the leaders who looked dangerous with a 55 second advantage. But they were reeled back in with 14 kilometres left to race.
Niewiadoma then pounced with only Kennedy able to react. While the Queenslander gave it everything she had and was initally only seconds adrift, it just wasn't enough to bridge to the leader and Kennedy was caught by the approaching peloton two kilometres from the finish.
Spratt was full of praise for her teammate.
"Lucy had another outstanding ride, she put herself in that race winning move and was so close to catching Kasia, the climb was just a bit too short for her. It’s so exciting to see how strong she is already in a world class field and it’s a only a matter of time before she gets a big result."
But Kennedy, probably a little too hard on herself, had mixed feelings.
"I didn't quite tick off all my jobs, I'm definitely still learning to race at this level. We still ended up with two in the top ten which is a solid result."
"Chasing Kasia up the final climb was really exciting. I was just about there, I just needed the climb to go on a bit longer. To be chasing down a solo leader in a WorldTour race is certainly not what I expected to be doing at this stage so it's very motivating for the rest of the season."
"It was another tough race in very testing conditions and everyone worked really hard. A big result can't be far away."
