Hi, I'm Ricky with your Saturday morning Newsround.

Coming up:

Martin goes dolphin watching in Wales and...

The woman who caught Usian Bolt's shoe.

First up, it's the last day of the Anniversary

Games in London today.

Last night, Usain Bolt won the 200 metres on his return

to the track where he won Olympic Gold four years ago.

The Jamaican has struggled with an injury but last night

he proved that he's still got what it takes.

But Bolt said he's still got some way to go to be fully fit

for the Rio Olympics next month.

I'm training, I'm doing pretty well, everything's going smooth.

But I can tell that I need races, it's just one of those things.

How are you going to do that?

Just go to Rio and like last year, just run.

That's what I have to do.

Continue training and continue pushing myself in training.

Hopefully, it'll all come together.

And take a look at this.

After winning the 200 metres, Usain Bolt threw his shoes

into the crowd.

The woman who caught them couldn't believe her luck!

She's now the owner of a sweaty pair of Bolt's trainers.

Well, from one record holder to another.

Kendra Harrison from the US broke the 28-year- old 100 metre hurdles

world record with a new quickest time of 12.2 seconds.

But get this - that's Kendra's highlight of her summer

as the American won't be going to the Olympics

after failing at the US trials. going to the Olympics

Cycling now and Britain's Chris Froome is on his way

to winning his third Tour De France in four years.

This is despite the fact he crashed yesterday and had

to borrow a teammate's bike to finish the race.

Luckily for him, his closest challenger also crashed.

After getting back on his bike, Froome managed to increase his

lead to whopping four minutes, 11 seconds.

The final stage will take place in the French

capital Paris on Sunday.

Football now and the new England manager was finally

confirmed yesterday.

The Football Association finally confirmed Sam Allardyce has been

given a two year contract to lead the English team.

The former Sunderland and West Ham manager seemed pretty happy

with his new job.

Get that smile!

I can't imagine we can't get that smile.

Excuse me, I can't stop smiling cos I've got this job.

This is a job I've waited for for many, many years and I'm

absolutely delighted that I'm now sat in this privileged position

of being the England national team manager.

It's going to be a great thrill for me to take the team forward

from the nation's point of view and hopefully make everybody

so proud of the England team again.

Finally, each year scientists at the Sea Watch foundation lead

a week-long campaign at the start of the summer holidays to get

you guys and grown-ups out and about around the UK

to spot wildlife.

We've sent Martin to Cardigan Bay in Wales to join in with some

young dolphin spotters.

Cardigan Bay -

a coast dotted by fishing villages, seaside resorts and

beautiful stretches of beach.

But perhaps it's best known as the home of the UK's largest

population of Bottlenose dolphins.

Over the past 40 years, whales, dolphins and harbour porpoises have

been monitored by scientists and volunteers all around the coast.

And today, I've joined these guys who are taking part

in an annual organised watch here on the Welsh coast.

Seawatch's conservation work hopes to improve the protection of whales

and dolphins around Britain and Ireland by keeping

track of and identifying the individuals here.

Despite two hours at sea, not one dolphin appeared.

But that didn't stop these guys who are back on land to try

things a different way.

I've looked out there about five times and every time,

I'm convinced that I've seen a dolphin.

It's not, it's a wave.

Despite the disappointment so far, how are they feeling?

I quite like doing this sort of thing but I haven't really

done it much before.

I felt quite disappointed that we didn't see a dolphin but I'm

hoping that we'll see one later today.

I was really, really hoping to see one out in the wild

and jumping out of the waves.

29 species of whale, dolphin and porpoise have been

recorded in our seas.

13 species identified during whale and dolphin watches like this one.

So why is this so important?

Basically, we want to know what's out there.

We want to know where are they and when are they.

We need as many eyes as possible on the sea over the national whale

and dolphin watch and so, we'd like to encourage as many

people as possible to do that.

If anyone can go out there with their families and do

watches over that nine day period that starts on Saturday,

then the more the better.

The more data we get on dolphins and the more information

that we have to protect them.

We've now been looking for dolphins for six hours

and we haven't seen one.

Dolphins!

Woo-hoo!

They're playing round these two white buoys right there.

They seem to be really close.

This morning we didn't get any luck and I was quite disappointed

and I really wanted to see a dolphin by the end of the day and it just

shows that if you have patience and you wait and you look,

you will find it in the end.

It was well worth it.

There it is again.

That's all from me, but if you want to find out more

about a record breaking hot air balloonist then head online

where you'll also find the rest of today's top stories.

See you just before 2. Bye.
