GB's Daryll Neita looks chuffed to be in this final. She takes an outside lane. Big smiles as she waves to the camera.

Ooh, a light show. The Olympic rings are projected onto the track. This is fancy.
What a shame no-one's in the stadium to witness it first-hand.

Let's remind ourselves of the line-up.

4x400m mixed relay final

This is the thing about the mixed relay, it's not about the might and talent of individuals, it's about the team. The Polish team have gone back to running the man on the first and last leg, and my the women in the middle gave their guy the best opportunity.
It cerainly gave us the excitenent of the mixed relay in the swimming and triathlon earlier.
Sadly for the Brits they weren't on it from the off. They should have kept Cameron Chalmers in the first leg, it's all about being in the race. Sad, sad disappointment for Britain.
Great Britain 2-0 Ireland
Back to the hockey for a moment as we get ready for the women's 100m final.
And Hannah Martin has her third goal of Tokyo 2020. Ellie Rayer provides Martin with the perfect chance to double GB's lead and the 26-year-old says 'thanks very much', slotting it past keeper Ayeisha McFerran.
Only a miracle comeback could turn this around for Ireland now.

Half-time at the Oi Hockey Stadium.
Ireland found some rhythm in the second quarter, with Nicola Daly drawing a save from Great Britain goalkeeper Maddie Hinch.
