The March Hare – 19th to 21st March 2021

Friday, March 19, 2021 - Sunday, March 21, 2021. 08:00

March will see our friends at the Castle Tri Series, host the final race of their Winter Virtual Series, The March Hare (19-21 March). The January and February turn out has been fantastic, with over 700 athletes racing across the globe with thousands of pounds being raise for charity. Let’s finish the winter season and lockdown with a bang and make this the very best yet!

The March Hare features brand new swimming distances and a brand-new partner. CES Sport have generously donated a beautiful pair of wheels into the event’s ultimate kit bag which is now worth a whopping £1,200. Everyone entered into the race has a chance to win, so don’t miss out!

This will also be the 10th ever virtual race from the Castle Tri team. They started their virtual races last Easter, when the world went into lockdown. What started out of necessity, has grown into a fantastic part of their community and will continue as a very special part of their race calendar each year. When unable to meet in person, the community have stayed connected and kept motivating each other from a safe distance. Thank you to everyone who has taken part and supported the events.
