Found a few more of the first girl. Looks like the first pic is where she decided to take off her knickers which I love;)

Few more

Also found a few more of the "other" girl from the first post I got mixed up with! First pic she still has her pants on...until she changes her mind ;-)

Few more. I know there are similar nude and dressed threads but I do prefer separate pictures rather than the joined pics

Here's the only one I have of the 'rainbow'hair' girl, but I have seen others.

Thx, Everard. Attached is what I found. As the sequence starts, she and her boyfriend (or good male friend) are fully clothed on the sidelines watching the particpants. She looks pensive, and he is shirtless. In the second shots, she is staring back toward him (where he is unseen). She is opening her bag. In the shots after this, they are fully nude and walking along with the others. The last shot I'm posting is a collage of shots that includes ones that I don't have high-res versions of.

Great find. Great pics!

Okay, three more. The one I have tagged #5 is my favorite because it is a full-on shot and she is smiling. The other two have her in motion.

This girl started 3 rides in 2015 wearing her bra and pants, Cardiff, London & Brighton that I have seen on here. By the middle of the ride she had removed her bra, and whipped her knickers off! These are the best pics I`ve seen of her, would love a full on frontal shot if anyone has any, lovely boobs and what looks like a glorious shaven fanny!

Two girls WNBR 2013 & 2014
 

I'm not sure if we've ever sorted this issue out. The two girls, at first sight, look the same but then detail, detail.

What is intriguing is that both followed the same sort of procedure. Hired bike from same company. Started ride with knickers then stripped. Both accompanied by male friend who was sometimes naked, but usually not.

I have many images of both ladies/years.

Here is a sort of timeline for 2013, and to help ID, two profiles, one from each year. The knickers on photos are Park Lane. I have always assumed the mounting of the bike occured when knickers were removed, anyobody know. These appear to be on the North Side of Westminster Bridge.
