If not, I exhort you to take a look. It's a gold-medal feelgood tale of the Games that will be long remembered along with the heady decision by two friends and sporting rivals, Gianmarco Tamberi of Italy and Bahrain's Mutaz Essa Barshim, to share the men’s high jump title rather than try and rip shreds off each other in a de-escalating jump-off at the end of a muggy and exhausting night of competition in which they could not be separated.

Parchment, 31, who won bronze at the London 2012 Olympics but missed the Rio 2016 Games due to injury, recalled how, in heading off for his semi-final on August 4, he had been listening to music on his phone and got onto a bus at a stop where he had seen the words "Athletics Stadium" displayed.

As the bus pulled up at its destination, however, the hurdler realised he was at the Sea Forest Waterway venue where the rowing was taking place.

All the official Tokyo 2020 cars were booked and the suggested standard procedure in such cases - taking a bus back to the Olympic Village and then another to the correct stadium - was a no-no.

"If I had done that," Parchment said, "I wouldn’t get there in time to even warm up. I had to find another way. I was trying to get one of the branded cars for the Games to take me, but these people are very strict and adhering to the rules, and I would have to have to book the car from beforehand to get it to leave.

"I saw this volunteer and I had to beg, ‘cause of course she is not allowed to do much, and she actually gave me some money to take one of the taxis. And that's how I was able to get to the warm-up in time and had enough time to compete."

Parchment had finished second in his previous day's heat to the clear favourite in his event, Grant Holloway of the United States, who earlier this year broke the world indoor 60m hurdles record of 7.30sec set in 1994 by Britain’s Colin Jackson, and then, at the US Olympic trials, came within 0.01sec of the 2012 world record of 12.80 set by fellow American Aries Merritt.

In the semi-final he replicated that result, as Holloway won in 13.13 and Parchment took the second qualifying place, equalling his season’s best of 13.23.

In the following day’s final, the two men once again finished first and second - but on this occasion Parchment, who had only earned the third Jamaican qualifying place, produced a gold medal-winning run, coming home in 13.04, with Holloway taking silver in 13.09.

So the next day he documented setting out from the Athletes' Village for the Sea Forest Waterway - "to find the Good Samaritan".

And as the post shows, he did so, catching up with Tiana, the Samaritan in question, and thanking her.

"You were instrumental in me getting to the final that day," he told Tiana, before repaying her, giving her a Jamaican shirt and showing her the gold medal he had eventually earned.

The volunteer's act of kindness was praised by Jamaica's Prime Minister, Andrew Holness, who shared the video on Twitter and wrote: "Every Jamaican knows that gratitude is a must. @ParchmentHansle demonstrates that perfectly here."

And the country's Tourism Minister Edmund Bartlett has invited Tiana to visit Jamaica, telling The Gleaner: "It is selfless what she did; one would not know what the outcome would have been."

By the by, I fully empathise with Parchment’s Tokyo transport trauma, albeit that the mix-up I endured merely caused me to miss a press conference. A switch in schedule meant me needing to find my way rapidly to the Tokyo Olympic Stadium – the billed venue for the presser.

I got there without a problem, only to find that I should have been at the Olympic Stadium. In Tokyo. Venue for the Opening and Closing Ceremonies and Athletics.

Not be confused with the Tokyo Olympic Stadium, which was of course venue for rugby sevens and badminton.

And as I had not gone through the venue booking system, I was not officially able to pass through security with my fellow travellers and install myself in the press room for a remote holding operation.

Too late, far too late to return to the Main Transport Hub and then get another bus out to the... Olympic Stadium, Tokyo.

My thanks were owed to the volunteer who led me over to the admin office and installed me on a chair next to a power source and with access to Wi-Fi. Lacking an Olympic gold medal at that particular moment I searched my bag and found a slightly wonky badge from the 2019 European Games in Minsk. For which she seemed touchingly grateful.

Turning back to the Parchment story, had it not been for the young woman’s generosity at that moment the high hurdler could have found himself as one of the numerous figures committed for eternity into the Olympic abyss.

The most infamous example occurred at the Munich 1972 Olympics, where the nightmare that Parchment began to feel a part of was experienced in full, traumatic fashion by the two top US runners in the men’s 100m, Eddie Hart and Rey Robinson.

Both men had equalled the 9.9sec world record of of the time - achieved by fellow countryman Jim Hines in winning the 1968 Olympic title in Mexico - and their times had been set at sea level in Eugene.

Walking through the Olympic Village shortly after 4:15pm on August 31, Hart saw 100m races being shown on a TV monitor in the ABC studios - and it soon became clear that these were the quarter-finals he was due to run in himself, but which he was not expecting to take place until later in the day.

At one point he saw his own name on the screen next to the initials "N/A" , standing for Not Available.

Nightmare.

He, Robinson and the third-placed runner at the US Olympic trials, Robert Taylor, were driven to the Olympic Stadium at top speed, but for the first two it was too late. Taylor arrived just in time to compete without a warm-up, and managed to qualify.

An appeal by the US team failed and the eliminations of Hart and Robinson stood.

The blame fell upon the sprints coach Stan Wright, with an assumption being made that he had made a mistake with the 24-hour clock and mistaken the start time, 16:15, for 6:15pm.

In fact Wright had been working off a year-old schedule that had not been revised as it should have been.

An investigation for the United States Olympic Committee later cleared Wright of any blame - but not before much opprobrium was heaped on him, particularly after he had been taken to task by interviewer Howard Cosell on ABC.

The report lays the blame on the late amendment to the schedule by the International Amateur Athletics Federation not being conveyed effectively to the responsible coaches.

That it was a more general misunderstanding is given credence by the fact that Valeriy Borzov of the Soviet Union, who went on to clock 10.14 in winning a final where Taylor claimed silver in 10.24, later admitted that he nearly missed his quarter-final.

Eighteen years later, Hart - who had the consolation of anchoring the American 4x100m relay team to gold in a world record of 38.19sec -  told Jim Murray of the Los Angeles Times: "Actually, it was the most disastrous thing that ever happened to me in athletics, but as a result of it, I think I’m a better person. It comes up all the time.

"At first, I tried to duck it. But it’s a part of sports history, like the guy who ran the wrong way in the Rose Bowl, and you learn to live with it. You can drown yourself in bitterness or self-pity. I don’t choose to."

Thanks to one kind-hearted Tokyo 2020 volunteer, that was a choice Hansle Parchment never had to make.
