Cowman Triathlon 2021

We are delighted to be back on the 31st July and the 1st August 2021 for the Cowman, Calfman and Stampede triathlon events at the stunning venue of Emberton Country Park.

The Cowman is a middle distance triathlon (1.9km swim, 90km bike, 21.1km run) and will take place on Sunday 1st August.

The Calfman is half of a middle distance (900m swim, 45km bike, 10km run) and the Stampede (introduced in 2018) is a sprint distance (750m swim, 22k bike, 5.25k run). These events will take place on Saturday 31st July.

The swim takes place in the lake adjacent to the sailing club, with the bike course heading out around the local area (2 laps for Cowman, 1 lap for Calfman, short lap for the Stampede), and the run course circulating the lake featuring both on- and off-road sections (4 laps for Cowman, 2 laps for Calfman, 1 lap for the Stampede).

This event will be taking place in a time-trial format as per BTF guidelines.

The events can be tackled as an individual, or the Cowman and Calfman can be done as a relay team of two or three.

All athletes will receive a bespoke eco-friendly wooden medal and a finisher T-shirt (Calfman and Stampede athletes only) or a hoody (Cowman athletes only).

Time-Trial Format

Based upon BTF proposals outlined in 2020, which we successfully implemented with our Cowman Duathlon event, this event will be run in a time-trial format. This means you will have isolated swim times, transition times, run and bike times added together to give you an overall finish time. This is just one of the number of measures taken to ensure a COVID-19 safe event.

Of course, our wish is to host an event as close to ‘normal’ to our traditional Cowman Triathlon as possible, so if by July/August 2021, social distancing is no longer a necessity and our event permit allows, the event shall take place with a mass start and a non-time-trial format once more.

We ask that athletes wear the appropriate face coverings when collecting their race packs from registration and respect social distance guidelines when around the venue.

If you begin to feel unwell leading up to the event or have any symptoms of COVID19 we ask that you forfeit your place and do not attend.

If the place you live in is put into tight restrictions inclusive of travel restrictions, we ask that you abide by government guidelines and do not attend the event.

A more detailed description of our COVID-19 measures can be found HERE.

Big Cow Sports are proud to partner with a charity that makes such a difference to people with life limiting illnesses and their families. Please consider helping us raise vital funds either by making a donation or taking part in aid of Willen Hospice and raising sponsorship.

About Willen Hospice “We are proud to be one of the best-loved charities in Milton Keynes, because of the difference we make for people with life-limiting illnesses and at the end of their lives. While we can’t change the diagnosis, we can improve the quality of life of our patients as they face and come to terms with their illness. We help our patients to live as well as they possibly can, we listen to their needs and we also support their families. Dedicated teams provide a range of support including treatment at the Hospice or in patient’s homes; bereavement support for family members; and therapeutic services. We also work closely with GPs, hospitals, community nursing staff and social workers to make sure that our specialist care is practical, informed and supportive at all levels.

Our vision is to always be there to care. To provide that care free of charge, we rely on the generosity of the local community in helping raise £4.7 million every year – that’s £9 every minute of the day.”
