Well, good luck to her, but i fear it's bluddy night on impossible
and as for being aerodynamic.... nooooo... with those wheels.... never, and the frame is just tubing
i can see a use for the much maligned and long forgotten shimano 'biopace' chainrings...
at the sort of speeds she'll be doing... aerodynamics (even with the winds she'll be pushing into) are not an issue.....
as its mainly uphill, into a very strong headwind (at least until she reaches the inner plateau), and pulling her own body weight on a sled, well.... its such a tall order
and.. in case you wonder if i'm talking my usual b*llocks.... i did spend 7 months on the british antarctic survey (ok, I was only there to ensure the twin engined otter plane was airworthy) and did experience the incredible extremes of weather that happen at the bottom of the world.
luck will be the deciding factor on this enterprise.
