Having made her debut back in 2003, Clark now stands second on the all-time list of appearances for England Women - former hooker Amy Garnett leading the way with a round 100.
And she's looking to surpass that mark at this summer's World Cup in France.
"I've really enjoyed my time [with England] and I want it to go on as long as possible," Clark said.
"I've had some very good experiences on the way and I've made some great friends. It's been wonderful to represent my country.
"[Becoming the most capped player ever] is definitely a goal. The first one is to win the World Cup because I want to become a world champion. Amy Garnett is a hero of mine too, so if I can get a couple ahead of her that would be fantastic."
