Enjoying a well-earned glass at the Aperfield Inn, possibly London’s highest pub, half a mile from #Bromley peak. Thanks to Jack Cornish for excellent navigation today. 30 miles down, far too many to go...

Not saying it was cold in the fields of #Bromley last night, but that’s frost on the tent. Time to warm up with a coffee... #SmogGrahamRound

Westerham Heights, 245m, highest point in #Bromley and all London. Next stop Croydon...

Behold, Botley Hill, highest point inside M25 but not a London peak because, we’ll, it’s not technically in London. #SmogGrahamRound

Just arrived in #croydon, London’s most underrated borough

In #Croydon, they honour their peaks. Why aren’t more boroughs doing this? Next stop: Sutton.

Sutton inside so strong. Sutton peak conquered. It’s Kingston next, followed by Merton. #SmogGrahamRound

Kingston Peak, Telegraph Hill. Locked gate and fly tipping: 1/10. Just Merton to go today.

Merton peak, finally. Long, long day.

The peak of Wandsworth (60m), a hill close to the Windmill. Most people assume this is Merton, but it’s actually Putney Heath in Wandsworth. Next stop: #Richmond

There is some debate online as to Richmond’s true peak. Some think it’s the trig point; others think it’s the higher but possibly man-made King Henry’s Mound. To cover all bases, I’ve visited them both.

Heading up the Thames Path to Vauxhall before heading south the end/start I’m Southwark/Lewisham. About 17 miles to go for South London Smog Graham Round.

Team Oxford getting ready for the Boat Race this Sunday. Putney Bridge, 15 miles to go (for me, not the rowers)

Made it to Vauxhall Bridge to be greeted by Jack Cornish and @MrGeorgeBull. Now just six miles south to the final peak of the South London Smog.

One final climb on the Green Chain link to the mighty peak of Southwark/Lewisham where it all started

South London Smog Graham complete. 3 days, 95 miles, 12 peaks. Someone fitter than I should complete the full Smog. Now for a pint...

London peaks are so hard to beat... Honour and a privilege to walk to the highest point in #Brent with the legendary Feargal Sharkey, talking rivers and rock’n’roll. Podcast to follow next week.

NEW EPISODE: The final episode of London's Peaks is now live. And what a way to go: chatting rivers and rock'n'roll with the irrepressible Feargal Sharkey. Thx to @IsaacWilliamsHQ and @MrGeorgeBull for support early on and to you, of course, for listening podcasts.apple.com/gb/podcast/31-…
