Jess Walker is through to another Olympic final.


  The Brighton-born sprint canoeist qualified today for the K1 200 medal race at Eton Dorney tomorrow morning (10.14am).


  Walker was fourth in her heat, with six going through, then improved into second place in her semi-final for automatic qualification into the eight-boat final.
 

 Walker, 22, was part of the GB team of four that finished fifth in the K4 500 earlier in the week.
