Also, she doesn't do much climbing, so her w/kg doesn't matter as much as her absolute power, which is somewhere in the 160w range, IIRC.
Although I always ride off from the front of the C Pace Partner unless I am mindful of the gradients, It seems like a huge jump to me to hang on the the B rider group. I guess because its near or closer to my threshold power-- but after 15 minutes I am toast.
I wish there was a C+ or B- option.
