I went for a “gentle jog” yesterday with the intention of doing a three or four mile run, enjoying the lazy afternoon sun after ushering in the beginning of the football season watching Chelsea narrowly beat Man United in the Community Sheild – a game which is really nothing more than a pre-season friendly, but always seems to crop up at the end of the season as “trophy” for whoever won it!
So having watched United beaten - it seems that the last time I watched them that happened as well – I decided that I would go and do a gentle jog round my local reservoir for a couple of laps, enjoy the sunshine and get in some exercise having spent most of the day either doing chores (cut grass, cleaning out guinea pigs, wash clothes) or sat on my bum shouting at the television (clearly Ballack fouled Evra, why didn’t the referee stop the game?).
After having run for one lap – which is about 2.3 miles – I decided that I was still feeling energetic and could quite easily do another lap. After all, the sun was out, there were plenty of people out walking their dogs, even some silly people swimming in the reservoir, and various sailors and wind-surfers all enjoying the sun and above average breeze.
I started the second lap, checking my watch to see how long it had taken me to run the first lap – just over twenty minutes, putting my time at a smidgen under a ten-minute mile pace. Fairly gentle pace, but as I’m building up for the Bath Half Marathon in March next year, I’ve got best part of six months to build up speed.
My main aim at the moment is to simply get some stamina back, as I’ve spent most of this year doing weight training, some short runs (2,3,4 miles) and a fairly hefty amount of sprint intervals or high intensity interval training on the treadmill. I feel I need to get used to running for long distances and used to running for long periods of time, as most of my running this year has been twenty five minutes or less sometimes!
After completing two laps, my time was on just over 45 minutes, which meant I wasn’t noticeably slowing down. With that in mind, and the fact I was still feeling energetic, I decided to complete a third lap. It was during this third lap that I started to feel the effects of the previous two laps, and the low carbohydrate diet that I consume – I was starting to flag a little – but I managed to complete the lap without any problems and the speed didn’t drop either. I completed all three laps in just under 70 minutes!
In fairness I felt much fresher than I would have expected, having run seven miles by the end of the three laps, but I can see that if I am to achieve a sub two hour time in the half marathon I am going to have to improve my stamina to the point where I can run 13 miles comfortably. After I’ve got to this stage, I will have to work on improving my speed.
To achieve my stamina, I plan to do a long run every Sunday, increasing the length by 1 mile every fortnight, until I have run two half marathons on consecutive Sundays. Once I’ve achieved this, I plan to work on my speed.
To improve my speed, I’ll be doing speed intervals on the treadmill, such that my recovery speed is the average speed that I wish to run at for the duration of the half marathon to achieve my desired time – approx 1h50. This will be about 8.5 min miles which is 7 mph or 11.75 kmh.
In addition to this I will start in January running my long runs at the 8.5 min mile pace so that I get used to running at that speed. Roll on six months of hard training to get a good time at next years Bath Half!
