Eilish has got a good finish but she slightly banking on this. She has run a long way round - way out in lane two.
Sprint
Becky James feathers the accelerator on the back straight.
Zhong Tianshi has kept a little in reserve, finds her second wind, but James has track position and slingshots off the final bend to take victory against the world champion.
A big result to start the afternoon for Team GB.
Next up is James' team-mate Katy Marchant.

Almayaz Ayana is miles away just like she was in her world record breaking 10km earlier this meet.
She wants the double.
Track Cycling
Little known fact: Laura Trott's pre-race psyche-up is actually a Portuguese language course.
"El leo come el pao."
First up, though team-mate Becky James - silver medallist in the keirin - is up against world champion Zhong Tianshi in her quarter-final.
James to chase in the first of their three run-offs.
Women's 5,000m - Heat 2
Steph Twell looks strong in the front. Eight laps to go.
Eilish McColgan is sat at the back but it's not a pace she can't keep up with.
If you can’t remember a recent record in a field event – discus, shot put or long jump for example – don’t worry, your memory has not failed you.
The records books for field events have barely been troubled for 20 years. Out of all eight throwing and jumping events only one men’s record, for pole vault, has been broken since 2000.
Our friends at BBC Worldwide have produced these interesting graphs which highlight this very fact.

British runners in this include Eilish McColgan and Steph Twell.
Both have overcome horrific injuries to be here.
And they are off...
Should be a quicker pace in this heat. Knowing the time to aim for will help them all run a tactical race.
If they are able to run 15:20 then the top 10 will make the final and Brendan Foster believes both Brits can do it...
K1 200m
New Zealand's Lisa Carrington defends her Olympic kayak 200m title with a dominant display in the final.

Poland's Marta Walczykiewicz took silver in 40.279 and Azerbaijan's Inna Osipenko-Rodomska claimed bronze in 40.401.

Good to see all the GB Olympic pool swimmers down on Copacabana beach today to cheer on team-mate Jack Burnell.
As you can tell from their social media accounts they're now very much 'relaxing' following the completion of their races and not all look entirely fresh, but they're here and that's what counts.
Team leaders looked happy when 'Burnell sixth' flashed up on the scoreboard. Well placed after one lap.
Women's 5km - Heat 1
The second heat is about to start but the results of the first are in...
The five automatic qualifiers are:
Hellen Obiri - Kenya in 15:19.38.
Yasemin Can - Turkey
Mercy Cherono - Keyna
Shelby Houlihan - USA
Susan Kuijken - Netherlands
GB's Laura Whittle is in 10th and is unlikely to make it through as a fastest loser but she says she was determined to enjoy it which she did.
"I am just really happy to have been here at my first Olympics and to run on the track. I was a bit nervous before but then saw my family and they waved at me and it calmed me down.
"I really enjoyed it despite probably not being fast enough to make the final"
Marathon swimming
More than forty minutes into the men's 10km and Jarrod Poort of Australia is still out in front by more than a minute after a rocket-powered start.
This was an incredibly gutsy move. If he can make it stick, well...
The chasing pack behind have slowed with Tunisian Oussama Mellouli unwilling to keep doing all the donkey work on the front.
Time for some leadership among the peloton. Time for Great Britain's Jack Burrell to step up?
Women's 5,000m - Heat 1
There is a little fracture in this race now as GB's Laura Whittle drops back.
It's a familiar sight with the Kenyan athletes now setting the pace at the front.
Just a reminder, there are five automatic qualification spots in each heat and then 5 fastest loser places are available for the final.
Women’s kayak double 500m
Gabriella Szabo and Danuta Kozak of Hungary hold off a late charge from Germany's Franziska Weber and Tina Dietze to take gold in the women’s kayak double 500m.
The Hungarians crossed the line in one minute 43.687 seconds, just 0.051secs clear of the Germans.
Poland's team of Karolina Naja and Beata Mikolajczyk took bronze.

British athlete Laura Whittle is at the front of the chasing pack and closing the gap.
"If she can WHITTLE that down to a smaller group at the front she will be doing herself a lot of favours"
Paula Radcliffe is on fire today...
Women's 5km - Heat 1
Amazingly there has been a false start!
It seldom happens in long distance running - they don't even use the technology to check reaction times if they needed to...
"That's because we don't have reactions" says Paula Radcliffe
You said it, not us.
But they are under way now and the Japanese athlete Miyuki Uehara has a massive lead already...
Laura Whittle, Steph Twell and Eilish McColgan run in the heats of the women's 5,000m today, the first of which starts about now on BBC Two or online.
Your commentators Andrew Cotter and Paula Radcliffe are ready.
