Me and Katie run 16 miles across London stopping for a dip in three ponds on the way.

My good friend Katie King takes on the Underround challenge devised by Rory Coleman http://www.rorycoleman.co.uk/Events_underround.asp?nid=109&pid=58 which involves running a marathon while visiting 42 London Underground stations.

Today I went for a run with American comedian Liz Miele. She's run 12 marathons, so I invited her to come for a run with me through East London.

You can hear some of Liz's stand-up if you catch one of her gigs while she's touring the UK, or in iTunes and Youtube. Have a look at her website for details.

I meet adventurer Anna McNuff to go for a run and chat about her upcoming challenge to run the length of New Zealand via trail.

You can follow Anna's challenge on Twitter and via her Facebook page.

In the second part of this podcast I finish the year off with a New Year's Eve marathon (and my first trail marathon) with my friend Katie.

The link between beer and running goes back a long way. I invited a few friends to go on a beer run through some of my favourite pubs in London to discuss the bond between beer and running. Rick Pearson from Men's Running tells me about his recent beer mile attempt.

After a cancelled ferry, some panicked phonecalls to the race HQ and a few favours called in to pick up our bibs, we finally made it across a stormy Irish Sea and to the start line of our second marathon in one weekend. Here's how it went.
