allows users to find information on events, sign up to races, and begin fundraising.
It also provides tips on training and features a community section where users can share their stories and photos. The new site replaces a legacy website which was built several years ago.
Speaking to Brand Republic, Adam Forster, senior project manager, internet and new media team, said Cancer Research UK was striving to compete with other charities in what is a very competitive sector of fundraising.
Forster said: "We first launched the site five years ago and at the time it was cutting edge. But in tandem with Essence we've drastically brought the running site up to speed.
"We wanted to engage with the emotional side of why people choose to take part in events but also keep it simple to use."
Essence developed the site using its own content management system Fig.
Richard Mooney, head of design and build at Essence, said the team had looked to provide a number of different messages with the rebuild to engage users who may be running for different reasons.
The news comes after Essence hosted its second annual autumn event yesterday at The Soho Hotel in London.
The event gathered together speakers including Jon Mitchell, sales director UK, Spotify, Tim Boddy, executive director, European telecoms investment research Goldman Sachs, Dan Cobley, senior director of marketing, north and central Europe for Google, and Sean Cornwell, vice president international for eHarmony.
