They're regular faces at Cheltenham Festival and Royal Ascot, and now Zara and Mike Tindall are doing their bit to help fellow sports fans in the UK get back to events.
The Queen's granddaughter, 39, and her ex-England rugby player husband, 41, both trialled a new rapid 10-minute Covid-19 test and uploaded their results to a digital health passport.
The couple, who have spent lockdown at their home on Princess Anne's Gatcombe Estate, were filmed taking the tests at the stables on their farm in Gloucestershire.
Both were relieved the tests came back negative, and the Tindalls are believed to have since travelled to Balmoral to see the Queen, reports Hello!.

Zara winced as the rapid pin-prick test was administered, which detects coronavirus antibodies and was performed under Covid-19 safe practice by Latus Health Care
Former Equestrian World Champion and 2012 Olympic Silver medalist Zara and Mike took the BioSure tests in their role as ambassadors for Manchester-based cyber technology company VST Enterprises.
They then uploaded their results onto their VHealth Passport - which has been developed to help get sports fans back into major events and stadiums - where they appeared within seconds.

The couple are taking part in a pilot scheme called FANS ARE BACK, which is being put to the government to get football, snooker, rugby, golf and equestrian sports fans back into stadiums and major sporting events next month.

The couple told how they uploaded their results onto their VHealth Passport, which has been developed to help get sports fans back into major events and stadiums, where they appeared within seconds
Zara said: 'This is a really exciting new technology that has such great potential for the equestrian world. For riders, who are travelling all over the country, and to other countries, this gives reassurance that they have been tested and are negative for Covid.
'For those working on events including support staff, volunteers and the fans themselves it gives the confidence to come back to the sport we love and have the big events running again.
'I found the whole experience of taking the rapid test and using the VHealth Passport really simple and quick to use and I hope with more people using it we will be able to get our sport back up and running and people enjoying it again.'
Mike added: 'Zara and I both took the test which was literally one minute to administer a blood sample and run it through the BioSure rapid test kit, with our results back in less than 10 minutes.

'The VHealth Passport is test agnostic, so it can work with all and any approved Covid-19 testing kits or lab based testing around the world.
'Our negative test results were then uploaded to our VHealth Passports in under five seconds and it means we get a green tick on a traffic light system on the VHealth Passport app on our phones.
'What this does is give people who use the The VHealth Passport system confidence that the people around them are also doing the same thing in a sporting event and have tested negative. Ultimately it's about getting the fans back safely into major sporting events.'
FANS ARE BACK is the brainchild of entrepreneur and VST Enterprises CEO Louis-James Davis, 32, who invented the VHealth Passport. VST Enterprises has recently submitted this pilot programme to Number 10 and the Department of Culture, Media and Sport.
Former Sports Minister Richard Caborn has widely supported the initiative and believes that a system of testing and health passports is the right way to get fans back spectating at British sporting events.
How does the rapid test and health passport system work?
The rapid test kit takes one minute to administer to a sports fan or a professional athlete, and gives test results within 10 minutes and a 98.7 per cent accuracy testing for three different antibodies IgG, IgA, IgM.
In particular the IgA line can detect and pick up infection as early as three days from exposure.
The test kit, which comes with a GDPR compliant and VHealth Passport, will be priced at £15 making it a game-changer for sports fans across the UK.
The unique attributes are the speed of the test, safety, accuracy and the secure VCode technology behind the V-Health Passport™ which authenticates and validates a persons identity - from their existing Government identity documents of passport and drivers licence - and their Covid test results.
It can also be used in other major events such as theatre, festivals and music concerts, where the principals of rapid testing and health passports using secure technology are the key to bringing fans back.
