Elizabeth Duggan is approaching one year in the role of CEO at Parkrun, the volunteer-led running organisation that is held up as a blueprint for sports participation in the UK.

Duggan and her team do a lot with a little. What started 21 years ago as one man - Paul Sinton-Hewitt - looking for company on a 5km run around Bushy Park in London has blossomed into a global community of 'fun-runners'. Parkrun welcomed its 12 millionth registrant recently and now operates weekend events - 5km runs and walks, as well as 2km runs for children - in 23 countries around the world.

In the next few years, Duggan anticipates reaching 800,000 weekly runners taking part. In this conversation, she explains the principles that have driven the charity's success.

The proposed merger between the ATP and WTA remains on the table, but as James Emmett and David Cushnan discuss, the time it's taking to finalise tells its own story.

On this week's show, there's reflections on conversations with Marina Storti, CEO of WTA Ventures, the commercial arm of the WTA, and Eno Polo, the new CEO at the ATP - and the challenges tennis faces with calendar congestion, balancing the demands of tournaments of various sizes, and player influence.

There's also time to discuss Casey Wasserman's decision to sell his stake in his agency, and the possible forms the sale could take, and as the NFL hires TMRW Sports to operate its planned new flag football league, how and where rights holders can create new IP, to make a greater footprint, expand geographically or fuel player development.
