The schedule fer the Womens 400M;
Mon 10.55, Round 1.
Wed 19.45, Semi-finals.
Fri 19.00, Final.
The schedule fer the Womens 4 x 400M relay;
Fri 9.40, Round 1.
Sat 20.14, Final.
I doubt any of the top 4 in the 400M betting will run in Round 1 of the Relay on Fri morning,
but if any of their countries make it in to the final, then I reckon after a full days rest they will run in the final.
