Sarah Walker has cycled through blood to cap off a successful weekend of BMX racing in Argentina.
The 2012 Olympic Silver medallist has backed up yesterday's third-placed finish – her first podium at a World Cup event in seven years – with an eighth at the final World Cup event of the year this morning.
"I'm super stoked to have been in the final [today] after being on the podium yesterday, very happy with how I'm performing," Walker told Radio Sport.
Walker says she raced within herself in today's final having seen a nasty crash unfold earlier in the day.

"There was a big crash in the quarter-final before me where they were washing [and] scrubbing blood [from someone's nose] off the track with a broom."
She says "it was a little bit real watching someone get stretchered off and then blood getting scraped off the track well you're sitting at the top of the 8 metre start hill".
"It was in the back of [my] mind for the rest of the day after that, and to be honest I was like, alright I've made two finals and I'm still in one piece and there's still a lot of Olympic qualifying to go so I'm going to race smart."
She eventually finished last in the final 3.349 seconds behind the Australian winner Saya Sakakibara.
It's no surprise Walker was determined to finish with a clean bill of health, having been involved in a raft of serious crashes herself throughout her career – including a horrific one in 2014, which left her with a concussion and six broken bones in her arm.
With the BMX season ended, Walker will now take up her other role with the International Olympic Committee Athletes' Commission, helping out at the Youth Olympics in Buenos Aires starting on Saturday.
She'll then resume her goal of qualifying for the Olympics when the BMX World Cup season gets underway early next year.
