 So when you think of firsts, there are a number that spring to mind immediately. First man on the moon, Neil Armstrong. First person to climb Everest, Sir Edmund Hillary. Although we'll never really know if Mallory and Irvin made it to the top before him. First person to run 100 miles on Zwift. First person to run a marathon in under two hours, Elliot Kipchoge. And the first person to run a mile in under four minutes, Sir Roger Bannister. And that happened right here on this very track. We are at the Ifleet Road track in Oxford. And we are going to run a Roger Bannister mile. So we're just going to do a warm up and then we'll get going. The problem with doing this session today is that yesterday Victoria and I ran a rather grueling 50k over the mountains in Snowdonia. So our legs are in no fit position to run a fast mile. Ideally we'd have come here fully fit, raring to go to break our mile PB on the Roger Bannister track. That's not going to happen today. So Victoria's doing her mile as we speak. So Victoria's just finishing her mile. There we are. Roger Bannister mile on the Ifleet track in Oxford. Well done Victoria. That was hard work after yesterday, wasn't it? From a UTMB World Series to a Roger Bannister mile. Right, I've still got to do mine. I've done five laps of warm up. I've got four laps from here now. And there we are. So that is our warm up. Our Sir Roger Bannister one mile and cool down done. About 6k in all. If you enjoyed the video, please do click subscribe. And comment down below what is your favourite first ever?

I can say that I'm still the overwhelming delight that it was a great surprise to me to be able to go today. And I think I was very lucky.
