first experience of triathlon. I’m a regular runner and I can’t remember how many races I’ve competed in. But running races are simple. You just show up and run. The biggest barrier you’ll potentially face is deciding whether to use two safety pins

, to give me a good indication of how I'll fare when I do the running leg of Team TW's relay triathlon in Hyde Park (in two weeks' time). But on completion, fighting the urge to be sick, absolutely spent and looking as white as a sheet, I was a full 2

this into this fartlek session this week:(2 mins easy, 30 secs hard, 1 min 30 secs easy,  30 sec hard) x 10. Cool down (10 mins)…where the 'hard' is 6:26 min-mile pace. The second area is my posture. I'm an incredibly inefficient runner, which I think is largely down

Time to work out a training schedule. The triathlon is now 8 weeks away. That's more than enough time to give me a fighting chance of running a sub 20-minute 5K. I'm booked into the Standard Chartered Great City Race, which takes place 4 weeks

With one week left until my running leg of the Hyde Park Triathlon, I visited Bupa's London branch for a fitness assessment. The aim? To find out if I've got the potential to run a sub 20-minute 5K at my current level of fitness and if not, then how
