Zara and Mike Tindall temporarily leave children for very special cause

The couple welcomed their second child in June

Zara Tindall is a hero. The Queen's granddaughter is taking on an epic bike ride with her husband Mike, just three months after giving birth to their daughter Lena. On Wednesday, the couple hopped on their bicycles at Herne Hill Velodrome in south London to travel to Dover for the day. 

Zara, 37, and Mike, 39, are raising awareness and funds for the Blue Marine Foundation, which aims to protect the world's oceans. The parents-of-two are keen sailors and have a deep respect for the sea. Zara said: "Our oceans are constantly under threat and it's for that reason that we are joining 100 brave cyclists in raising awareness around vital marine conservation projects like Blue's so that they can receive the funding and support they need." The group will travel to Monaco, but Zara and Mike are only taking part in the first leg.

Retired rugby star Mike added: "Both myself and Zara believe it's really important to help protect the oceans for our children and future generations to enjoy. Today, we'll be getting on our bikes to help Blue raise awareness for their fantastic conservation projects. The first leg is certainly going to be a challenge but we're hoping our competitive streak will help us through."

The couple welcomed their second child in June, after Zara sadly suffered two miscarriages. The Olympic equestrian has a passion for sports and was already back in the saddle this summer, competing in horse trials in her mother Princess Anne's home of Gatcombe Park, Gloucestershire.

Zara and Mike's elder daughter Mia is often spotted on family days out in the park with her cousins Savannah and Isla Phillips – the daughters of Peter and Autumn Phillips. Mike has since opened up about family life, telling HELLO! magazine: "Mia is very happy to a big sister, she is happy about that. We're doing alright at the moment. We've had a couple of bad nights with Lena but otherwise she has started off strong."
