This is The Guardian.

Today, the dirtiest race in Olympic history.

In the 90s, my friend and fellow journalist Don Phillips

was at the centre of the UK's dance music explosion.

By 2022, he had mysteriously disappeared

in one of the remotest parts of the Amazon jungle,

with his friend Bruno Pereira.

In 2025, so many questions remain.

I'm Tom Phillips, the Guardian's Latin America correspondent.

Listen to Missing in the Amazon from June 5th. The Women's 1500 metres final.

That being drawn to the attention of the crowd now in this stadium.

It was the penultimate night of the 2012 London Olympics, and Britain's Lisa Debrisky was waiting

in the athlete's tunnel for the most important race of her life.

I found it very scary, if I'm completely honest. It's a very hostile environment.

You're in a space with all these people that are about to step on that start line and give everything they've got to achieve their dream and their goal.

Coupled with that, you're in front of a home crowd and that home crowd in London was just something else.

It just felt very overwhelming.

For this, Lisa Debrisky of Great Britain,

so near to World Championship gold last time in 2009.

I felt very ready on the start line.

I was like, okay, this is it.

This is what we've worked for.
