(I posted something very similar to this on the Bridge to 10k forum, so apologies for any duplication)
When we start the C25K plan a lot of us believe that at the end of the 9 weeks we’ll be able to run 5k in 30 minutes, not an unreasonable belief given how the program is presented. We then get to a point in week 8 or 9 where we start to be bothered that we aren’t good enough because we are nowhere near this fast. I’m writing this post to try and give some perspective on that.
Firstly, only a small percentage of us manage 5k in 30 minutes by graduation. I’ve now been running for 2 years and am nowhere near that fast.
It’s unfortunate that speed seems to be the main metric people use to assess their performance. While that might be necessary if you're a competitive athlete, for the rest of us it can just be plain disheartening. I wrote this post to reassure you that speed is irrelevant, what is most important is that you enjoy your running and take pride in all the other achievements it brings.
This morning I set out to run 5k and started contemplating running speed in general and my speed in particular. I'm not going to put numbers just comparisons. The pace you can realistically achieve will depend on your age, weight, height, sex and lots of other factors. If I was to compare myself to a 25 year old man my pace would be glacial. If I compare it to another 65 year old woman it probably wouldn’t look so bad. But why should I (or you) feel the need to compare this very variable metric to anybody else?
The aim of this run was to take it easy, to go at an OK pace but not push myself unduly. Thinking in terms of effort, I was going for a 5 or 6 out of 10, no more.
I’ve run this particular route many times and know it like the back of my hand. For the first km it's always a matter of sorting out how my feet and my breathing interact, getting used to the act of running. The first and second km are both level grassy paths in good condition. I was consciously keeping my speed down. I've not been running 5k regularly so didn't want to use all my energy at once. By the end of the first km I was in a decent rhythm and running at maybe a 5/10 effort as planned.
The second km was easy. The Toxic 10 was out of the way. If you’re not familiar with this term it’s shorthand for the idea that it takes about 10 minutes for the body to get used to the transition from walking to running. It’s the time it takes for you to get into gear and for the joints and muscles and heart to start to work together properly. After 10 minutes or so things usually improve.
My rhythms had all come together, the sun was shining, the breeze was cooling me down, the path was flat and even, all was right with the world. I kept an eye on my heart rate as a means of ensuring I wasn't overdoing it. Km 2 was 23 seconds faster than Km 1. Despite all my 'speed doesn't matter' talk I found this cheering especially as my perceived effort was the same, 5/10.
At Km 3 the path changes. It's farmland, still level but rougher as the path isn't cut so close as the earlier stretch. You have to jump from side to side, trying to judge the bits with the least potential for holes that might cause you to trip. More effort, higher heartrate, same pace as Km 1, probably 6/10 effort.
At Km 4 the path meets a farm road, concrete with flat, firm edges. I slowed down to allow my heartrate to settle. I was able to look at the geese flying over the fields and the insects scurrying along the path. Then, I sped up a bit, quite a bit actually, it just felt right, the surface is good and the next bit of path is very safe to run. Then, we turn to go up to the sea wall.
The tide was in for once, so I stopped to take a photo and admire it. What's the point of being somewhere beautiful if you can't enjoy it? I spotted a big boat fender that the tide had washed in. These cost around £90 to buy new, so my husband scrambled down to the water’s edge and retrieved it. There was nothing to indicate who it belonged to but it was obvious why it had been abandoned. It was covered in little holes, as if a cat with very long claws had dug into it. This was my slowest km of all, 7 seconds slower than Km 1, despite sections being the fastest of the run. Effort was still around 5-6/10, even on the faster bits as the surface was so good.
Finally the last km. The path follows the route of the river, it turns left and right, is very narrow, has the odd dog poo plus people who need to be passed with a cheery 'Good morning'. I sped up, knowing I'd soon be able to get my breakfast. It wasn't as quick as Km 2 but was 11 seconds quicker than Km 1. The final 0.12 km were quickest of all, 28 seconds faster than Km 1 but then if you're only doing 120 metres it's not very far to maintain an effort.
So, what was my takeaway from all this?
The difference between my average pace and my fastest pace was about 1’15”/km. If I was running at my fastest for the whole 5km I still wouldn’t be anywhere near 5km in 30 minutes. Does that mean my run was a waste of time? Absolutely not. I had a decent session of vigorous exercise, well over the daily guidelines we’re told to aim for, so a definite success.
The fact I hadn’t stretched myself to my limits meant that I felt great once I finished. I hadn’t risked injury by subjecting bones, muscles and tendons to undue stress. I was going slowly enough to avoid trip hazards. Most of all I could enjoy it as the only person I was doing it for was myself.
To be able to run 5km at my age, at any age, is an achievement to be proud of.
OK, I’m not immune from being quite pleased with my personal best times but I was just as happy with the fact of my first 10 minute run, let alone my first 30 or 60.
On this run I demonstrated to myself that my pace was more affected by the terrain and what I was seeing than my fitness, level of training or anything else. Some days I might be trying to see how fast I can go (Parkrun lol) but that’s pretty rare. For all the other days it’s way more satisfying to just get out there and enjoy it. The fact you’re doing C25K is fantastic, don’t lose sight of just how amazing you are to have got this far (even if you’ve only got as far as thinking about it 😊 )
PS I'd like to try this again on a treadmill and see how that would affect anything, but as I don't have access to one that'll have to wait.
