Robbie Fergusson helped hometown team Ayr win a domestic double in 2013 before his career was interrupted by Hodgkin's lymphoma, an uncommon cancer that attacks the immune system.

The centre has made a full recovery and, while sevens is his priority, played 10 times for Glasgow Warriors last season.

Ross McCann is the odd one out in his sporting family, with his two younger, footballing brothers - St Johnstone midfielder Ali and Dunfermline Athletic forward Lewis - having chosen to represent Northern Ireland, the land of their father.

The wing, who also coaches the under-16s at Royal High School, famously scored four tries as Melrose clinched a domestic double before bursting on to the sevens circuit.

Acclimatising to yet another country should be come as second nature to Max McFarland.

Born in Ireland, with a Scottish grandfather, he spent six years in Russia because of his mother's work before returning to Ireland as part of Leinster's rugby academy then moving to Edinburgh in 2014.

Since making his Scotland Sevens debut that year, the wing has been on the books of Edinburgh, Munster and Glasgow Warriors.

Hannah Smith is another to come from a sporting family, having taken up rugby at Stirling County at the age of 17 along with her younger brother.

While flanker Matt retired at the age of 26 after being released by Glasgow Warriors, saying he had fallen out of love with the game, veterinary surgeon Hannah goes from strength to strength with Scottish Premiership club Watsonians, Scotland and now the only Scot in the Team GB women's sevens.

For most, the pandemic put their Olympic preparations on hold, but for Charlotte Dobson and the rest of the GB sailing team, it's been the opposite.

Completing "turbo" sessions via Zoom has become a regular occurrence for the Glasgow-born sailor who made her Olympic debut in 2016.

After linking up with Saskia Tidey Dobson in the 49erFX class, she will be looking to go further than her eighth-place finish in Rio.

Luke Patience has proven time and again that he has top sailing pedigree.

Despite changing partners three times since his last Olympic medal in 2012, notably and unfortunately in 2016 when partner Elliot Willis was diagnosed with bowel cancer, his standards have not dropped.

As he heads out into the Tokyo waters again in the 470 class, the one thing missing from his already bulging trophy cabinet remains an elusive gold.

Heading for her first Olympics, shooting star Seonaid McIntosh didn't have far to look for a few pointers, with sister Jennifer having represented Team GB at London 2012 and Rio four years later.

Jennifer and mum Shirley are both Commonwealth Games medallists, but Seonaid, coached by dad Donald, took the family tradition to new levels by picking up 50m rifle prone gold at the World Championships in 2018 and becoming the first British woman to be ranked world number one for the 50m rifle three positions event a year later.

Lockdown has limited McIntosh's ability to compete, but she will be among the favourites to become the first British female to win an Olympic shooting medal and the timing of the event at Asaka shooting range next weekend means that she could land Team GB’s first medal in Tokyo.

A serious knee injury had put Kathleen Dawson’s swimming career in doubt, but she fought her way back following surgery to break Scottish records in the 100m and 200m backstroke at Olympic trials to secure her place in Tokyo.

She claimed the European 100m backstroke title despite having to swim the final twice in Budapest and, with the third fastest time in the world this year, one wonders what colour of medal the keen artist might be painting in her mind.

Lucy Hope was a late call-up to the 30-strong GB swimming team heading to Tokyo.

The Edinburgh University student travels with more than just hope of a medal in her first Olympics considering she gathered four golds at this year's European Championships - in the 4x100m freestyle, 4x200m freestyle, 4x100m mixed freestyle and 4x200m mixed freestyle relays.

She managed to break the Scottish 100m freestyle record during the 4x100m relay final and then produced the only sub-two minute swim in the individual 200m freestyle at the British Swimming Glasgow Meet to book her place in the team.

Having been unable to afford a proper racing suit until he was 18 and having once been hit by a brick thrown at him on his way to training in Alexandria, Ross Murdoch knows all about being the underdog.

He sprang to prominence when beating favourite Michael Jamieson to win 200m breaststroke gold at the 2014 Commonwealth Games and world and European relay golds were to follow.

However, Murdoch has been public about "personal demons" in handling both success and failure after missing out on his favoured 200m breaststroke at Rio by finishing third at the GB trials and then failing to reach the 100m final.

Overshadowed somewhat by all-conquering Englishman Adam Peaty, he even considered retiring during lockdown amid a question mark over his long-term funding, but thoughts of redemption for Rio drove him on while realising he might have to produce the swim of his life to reach the final in his favoured 200m this time round.

Duncan Scott made his biggest splash yet in 2018, becoming Scotland’s most decorated athlete at a single Commonwealth Games with six medals and the first Scottish swimmer to win gold in the 100m freestyle.

However, his medal haul since winning gold at the 2014 Games is too numerous to mention here and he heads to his second Olympics looking to improve on two relay silvers last time round.

Scott has come a long way since attending Strathallan School on a sports scholarship and, while his best time at 100m freestyle is 10th in the world, he is top of the class at 200.

Despite being the daughter of a swimming coach, Cassie Wild threw herself into any sport to get away from the pool, including athletics, netball and basketball, but fell in love with the sport after watching the 2012 London Olympics.

Having moved from Ellesmere, she trains alongside fellow backstroke specialist Kathleen Dawson at University of Stirling and has improved on times that made her a double finalist at the World Championships in 2017, finishing sixth in the 50m backstroke and seventh at 50m.

Wild qualified for her Olympic debut by finishing second behind Dawson in the 100 and 200m backstroke at the GB selection trials and is ninth fastest in the world this year at the longer distance. What time can the keen baker cook up in Tokyo?

Former world number one Andy Murray is the only men's tennis player in Olympic history to win two singles gold medals, but a third in a row is a long shot in his fourth appearance - especially after Wimbledon champion Novak Djokovic confirmed his participation.

After the struggles to return to the world tour following his hip surgery in 2018, he has only played a handful of matches this season, exited Wimbledon in the third round and is currently ranked a lowly 102 in the world.

However, there were signs that Murray, who also won Olympic mixed doubles silver alongside Laura Robson in 2012, is at last on the road to recovery.

As they say, never hurry a Murray.

Like wee brother Andy, Jamie Murray is making his fourth Olympics appearance but only makes it this time as a late replacement for Dan Evans after the British number one was forced to withdraw when he tested positive for Covid-19.

It means the seven-time Grand Slam doubles winner will rekindle his partnership with Wimbledon mixed doubles champion Neal Skupski.

The pair competed on the ATP Tour last season, as well as for Great Britain at the 2019 Davis Cup, so a first medal to go along with his wee brother's is not out of the question.

Phew! Got all that?

An eventful few weeks are in store for those 53 Scots.

Good luck, and stay safe, to all heading for Tokyo.
