Intervals - time machine

I've now got a few weeks worth of miles under my belt, so today I did some intervals. Me and another bloke where I work went out at lunchtime and did six lots of fast running for 2 minutes, separated by jogging for another 2 minutes.

Einstein's theory of relativity states that objects going close to the speed of light experience time differently to those that are not. I'm not an expert on relativity or travelling quickly, but time was certainly altered today.

Every time we started running the fast bits, the 2 minutes seemed to take ages. Whereas when we were running a lot more slowly, each 2 minutes was up before we'd even started to get our breath back.

On returning to work, I sent an email to the journal Science, so that others could benefit from my groundbreaking discovery. I'm hopeful that time travel can be developed based around the same concept.

For the rest of the afternoon, I had a lot to do, so stayed in my running kit and ran round the office, trying to slow my time so that I would have more time to complete the report I was working on. Unfortunately, I had to nip back to the computer every few minutes to type another word.

By home time, imagine my surprise when I realised I'd only done about 20 words. I was also very tired. I can only conclude that the time machine effect doesn't work inside buildings. I will let Science know about this first thing in the morning. Actually, it will have to be at 10am tomorrow, as I notice I've got a meeting with my boss and the head of HR first thing. Perhaps they're interested in getting more people to try my experiment, or maybe moving me to an outside office.

Navigation - where it's at

This was my first chance to sample some of the delights of my club's winter navigation challenges. This one started in Hayfield and went for a very nice meander around the local area taking in four wall/fence junctions and the like. In total, it was about 9 miles.

I've not got a great sense of direction so thought it would be a good chance to develop my navigational ability. I was set off as one of the last runners, on account of my fairly good running ability - when I'm fit and I know where I'm going. Unfortunately, today I wasn't and didn't. I was also telling as many people as would listen, that I did some more cycling hill reps yesterday, so I wasn't going to be setting a good pace.

I was set off with a team-mate Darren, who seems to be running well after missing some of last year's races for a variety of reasons. For the first mile, it was easy enough to follow Darren and not really worry about navigation. I was thinking that this was kind of cheating. So it was lucky that he then ran off into the distance and I had to do some proper map reading.

In the end (1 hour and 36 minutes later), I completed the event and was rewarded with soup and cake from various Pennine members. I'd really enjoyed it, but hadn't done very well. In handicap terms, I think I was dead last. Even looking at time taken, I was a long way off the leaders and those who I should be close to. Darren beat me by over 20 minutes - nice one Darren. I'm hoping this will serve as a baseline from which I'll work up in future navigational events.

My main learning from today is this:

• Make navigational decisions while running uphill, even if they are a fair way ahead. I can read a map running uphill without having to slow down, but I can't do this downhill.
