Christine Ohuruogu’s farewell was a bittersweet affair.
The 34-year-old, who started running in this London borough as a young girl, dabbed her eyes a couple of times during the presentation of a photo collage of her career highlights and a ginormous bunch of flowers.
“It really does hit home on what I am closing the door on. There is always going to be a part of me that wishes that I was still out there,” she tells the crowd.
A standing ovation from the crowd for one of Britain’s real big-time performers. The higher the stakes, the more she thrived.

Women's high jump (from 14:09 BST)

Olympic heptathlon gold medallist on BBC TV
World high jump competition isn't at a high standard. Our girls really have a chance and Morgan Lake is gaining confidence and this competition, in this stadium, presents her with a great opportunity.
Women's 100m hurdles heats
Also competing in the 100m hurdles are Jess Hunter, Cindy Ofili and Megan Marrs of GB, plus plenty more of the stacked American stable.
Any of Queen Harrison (below), Christina Manning, Sharika Nelvis and Kori Carter could win.
Women's 100m hurdles heats
You won't find a better athlete in the world who hasn't won a major medal than Keni Harrison.
The world record holder is ludicrously good on her day but has no luck when it comes to the big occasion. She missed the Rio Olympics after a bad day at the US trials - think Cool Runnings - but smashed the world record in this very stadium instead.
She will hope for good things again today.
If you haven't read it already, our man Mike Henson's interview with Greg Rutherford is well worth a few minutes of your time.
Rutherford talks frankly about how he purposefully embraced the celebrity culture and opportunities after his London 2012 gold medal, saying he aimed to "hang onto the coat-tails" of Jessica Ennis-Hill and Mo Farah, his fellow 'Super Saturday' gold medalists.
He also has some strong words for the way athletics is run.
Here's Greg Rutherford being introduced to the crowd. No tears - yet.
A winning time of 50.31 for Steph McPherson. The British quartet were run out of it, with Amy Allcock and Zoey Clark running the exact same time of 51.36! That won't help the selectors when it comes to picking the team for Berlin on Monday...
Women's 400m
Anastasia Le-Roy is out fast for Jamaica in lane four and she looks a class act down the back straight.
Can anyone catch her? Steph McPherson steps on it round the top bend and it's a Jamaican 1-2.
Women's 400m (14:04 BST)
No Ohuruogu on the track anymore then but four Brits do go in this next race.
Anyika Onuora has the fastest time of the quartet this seaosn.

Melvin: Christine Ohuruogu - an absolute legend in British athletics. What a woman.
Christine has just been presented with something to honour her career after retiring. What a legend on the track - she won golds at the worlds, Commonwealths and Olympics.
Women's discus
No surprises in the early stages as Sandra Perkovic, world and Olympic champ, chucks the discus out to 67.24m in her fiirst effort.
Women's high jump (from 14:09 BST)
Katarina Johnson-Thompson follows up her impressive long jump display on Saturday (above) with a run out in the high jump. She comes up against fellow Brit and fellow multi-eventer Morgan Lake.
World champ Mariya Lasitskene looks the one to beat. She's the only woman in a strong field to clear two metres this season.

Every time Sophie steps on the track, it's like a time trial.
Women's T37/38 200m
Sophie Hahn: "I knew I was in good shape and it was a quick track. Hopefully I can be consistent, it's all about working in the gym this year."
Women's 400m (14:04 BST)
None of the medallists from the worlds or the Rio Games are on display today as four Brits go up against Courtney Okolo of the US.
Women's T37/38 200m
Sophie Hahn was the favourite and she shows just why! Dominant display from the Brit in a PB of 25.93. Another world record!
Women's T37/38 200m (13:50 BST)
This race is for competitors who have co-ordination impairments but have enough function to run, and is a mixed class event with T37 and T38 athletes. T37 athletes are judged to have more impairment than T38 athletes.
The strong favourite will be Britain’s Sophie Hahn (below), the T38 200m world champion who won Commonwealth gold for England over 100m on the Gold Coast in April and is also the world and Paralympic champion over the shorter distance.
Ali Smith, who is also a T38 athlete and will be making her GB debut in next month’s World Para-athletics European Championships in Berlin, will be one to watch.
Michael Johnson
Four-time Olympic gold medallist athlete on BBC TV
Kare was simply more powerful than anyone else today and very dominant.
