Background
That’s right I tried running a 5k without any cardio training since well… a long time. I think the last time I ran or attempted to run a longer distance was in the summer of 2022 when I attempted to do the training regime of Saitama, the fictional protagonist of an anime called One Punch Man for 30 days. For those of you reading that haven’t watched the show the premise is Saitama can kill any monster with one punch. The way that he got so strong is a mystery, however, what he has said to be his training was 100 push ups, 100 sit ups, 100 squats and a 10km run. EVERY. SINGLE. DAY. It’s a fun show that I’d recommend watching. When I attempted this challenge, I realised that by far the 10km run (well mostly walk in my case) was the hardest, and I had severely underestimated that part of it. Back to present day, like the smart individual I am, I thought let’s not learn from my past mistakes and sign up to a 5km parkrun on a whim the day before.
What inspired this.
It was a Friday (22/08/25) and I was bored as I only had 3 hours of work to do this day. Not being busy for me sucks, I get too in my own head and I need to do something to distract myself, to move towards something. For the past year that something has been trying to become stronger, hitting the gym frequently roughly 4-6 days a week. Exclusively trying to break my own strength PR’s in various lifts. Trying to bulk up and going with the advice of cardio is bad for your gains.
Anyways, I got up in the morning walked my dog, made him food, showered, ate and put on a YouTube video. Like the stereotypical member of Gen Z that I am. I have trouble eating without having something on in the background. Deciding I want to watch Magnus Midtbø attempt to complete one of the hardest triathlons in the world the Norseman with only 2 weeks training. Magnus is a very fit guy and he’s done multiple physical challenges before however this was an insane feat that he has called his hardest to complete. The Norseman is considered one of the hardest triathlons in the world for a reason. It is a 3.8km swim, starting the swim by jumping off of a ferry into the Norwegian the Hardanger fjord. Followed by a 180km bike ride through the mountains with the first 40km being uphill. This is then followed by a marathon (42.2km), which culminates with a 17.2km run up a mountain. Insane. Truly a mythical superhuman feat to achieve that. Spoiler warning in the next paragraph about Magnus’s video.
Magus managed to finish the race in 69th place out of 250 participants. I thought to myself now that’s something I want to try one day. I think the feeling after truly giving 100% to a physical challenge is one of the best feelings you can experience whether it be a Strength or endurance PR. I thought the feeling of conquering a challenge of the magnitude of a “Norseman” must be out of this world, a spiritual experience even.
Then I thought back to myself and thought I want to experience that too. In fact, I want to have the coolest dad lore I possibly can. I googled Magnus’s age and found out that he is 36 years old. Then thought I’m 23 if I start doing at least 1 physical challenge a month think of the number of experiences I will have experienced by the time I’m 36. The number of stories I could tell, the people I will meet along the way, the kind of person I could become. That got me excited. It gave me the sort of excitement I haven’t experienced in a long time. The sort that breaks the monotony of routine that I felt stuck in.
This manifested in me spending the next hour making a list of all the physical challenges I would like to complete before I inevitably die. Then I started to research any physical challenges that are happening around my area as I haven’t brought myself a car yet. The first thing I came across was a Hyrox event near me that was happening on the 20th of September, I have seen clips of Hyrox before and thought why not! I image this will be something I write a blog post on next. So, stay tuned! The thing is I couldn’t find many more events that were in close proximity, and right when I was thinking that a thought crossed my mind “Parkruns, I think that’s a thing let me google whether there is one where I live.” Low and behold there is one in my town! In fact, it’s in the area I used to do pull ups when I didn’t have a gym membership. But wait there is more! The next 5km park run is tomorrow. You can see where this is going. After telling my mum and making sure she would be able to drop me off I signed up.
Cheers to the start of making the dad lore I dream of one day having.
The Race.
Breakfast I decided to try something new. I find it quite funny in retrospect. Because I didn’t do any research on what I should eat before a run. So, I just made a toast with homemade guacamole and 2 poached eggs because it seemed healthy you know, something your local runner would eat in my mind. No idea whether they actually would eat something like that before a run though, it seemed like a good idea at the time and it was probably the right choice looking back on it as spoiler alert. I didn’t throw up.
My back was a bit sore this day, the night before I was doing a back day in the gym, but I was feeling good, excited and nervous at the same time. I didn’t know what it would look like or how I’d fair. My mum and I got in the car, when we arrived 10 minutes till the start, we didn’t expect there to be as many people as there was. I was treating this event as just a run just something to gauge my fitness level and practice for the Hyrox event I wanted to do next month. Having forgotten that a 5k parkrun is something that a lot of people train a long time for. That a parkrun is a lot of people’s final goal after a lot of hard work. For example, the couch to 5k initiative by the NHS which is a 9-week plan that many have followed to run their first 5k.
There were a lot of first timers me included, but it was mostly a lot of veterans. The atmosphere before the race was amazing everyone was so positive and supportive of one another. The event had a real sense of community. The original plan as I didn’t think the event would be so well organised was for my mum to drop me off and go. But when she saw how many people came and how official it was, she stayed and wanted to watch me race and support me through it, which I really appreciated.
I was quite overwhelmed by everything in a good way everything was so new but also so cool. A lot of people knew each other, and it was great to see so many people excited to try their best. The Marshalls and volunteers were very helpful and helped make me aware of how the whole thing would look like. Where to go on the course, how many laps of the course in our case around 2.5. Also reminding me that at the end of the race I would have to pull up the barcode I got when signing up for the run, so that they could register my position and time. From the little prep I did before hand I saw that you could also buy a wristband with your barcode on it for £20 which I decided to not do for this race as I had too little time. By the time I knew the bare minimum about how the parkrun was going to go we were all called to the start line.
After celebrating some of the milestones of some of the runners there who were on their 100th, 50th, 10th, 5th Parkruns, the head Marshall told us to line up, and we were off. I wasn’t ready for it when the start was called. Like the professional I am. I was still on my phone trying to get a stopwatch on, as a contingency if my barcode didn’t work for some reason. But I saw the positive in it for one I won’t have to worry about becoming lost at least as there was a lot of people in front of me.10 seconds or so into the race I was ready, stopwatch on, I put my phone in my pocket and started running in the crowd. I was near the back. I wanted to go slow because I had no idea whether I would even be able to run 5km. Feeling good, so far so good I feel like the first 100m was very relaxed and that I could maybe go a little faster. The energy in the crowd was making me want to push myself harder.
I started overtaking some people and getting in a rhythm. What surprised me and also impressed me looking back on it was that there was a volunteer every 300 metres. Encouraging the runners to keep going and being all around supportive. I said hi and thank you not out of breath yet. But I could already tell saying thank you latter on might be struggle, with me likely breathing like a Yorkshire terrier after a long walk of pulling and piping up to every big dog they see (subtle foreshadowing).
The first lap and a half went by slower than I thought, but I was going at a steady pace still overtaking people while also getting overtaken by a few people that managed their energy better than me. Or so I thought with some of them as I started to overtake them again and we would continually overtake each other, motivating each other. My nemesis (or I guess biggest competitive motivator haha) during the run was this one blonde middle-aged lady that must have overtook me like 5 times and visa versa during the run. As a self-identified gym rat that hasn’t done cardio in years, I can’t say I wasn’t expecting this.
Near the end of my first lap and a half I saw 2 people sprinting for the finish line, I was shook, because I realised these guys just lapped me. It was wild to see and made me feel inspired. During the run it wasn’t the only thing that inspired me, I saw so many older people that were ahead of me, a somewhat healthy 23-year-old guy. With them just chatting with each other while going faster than me. Chatting while I was utterly out of breath. What didn’t make me feel inspired though was the fact that I was only halfway through and I was already totally exhausted. It made me feel like I was in that one meme that goes “It was at this moment, he knew, he fucked up.”
It became less of a race for me, seeing how many people I can pass. But rather me challenging myself to not stop running no matter how slow I was going. Walking or stopping was banned in my head. Around 70-80% of the way to the finish I was totally dead. When I passed by volunteers saying good job I would let out a huhuh-tha=huh=you, or just nod. I was gasping for air too much to be able to talk and my hypothesis of this happening that I made at the begin of the race came true.
Nevertheless, with my mum occasionally coming up to me mid race supporting me with my sister who was on facetime with her, I was nearing the end of the race. I decided to pick up the pace and sprinted the last 70 metres. It felt good. I manged to overtake 2 or 3 more people. Volunteers shouting, “Watch out Sprinter behind you!” and other participants who had finished saying “Nice strong finish”. I finished; I gave 100% of what I thought was possible for me and then some.
One of the volunteers gave me something to give back, I was too exhausted to properly hear what she said apart from scan your barcode. I know now that what she gave me was a token. I was too tired to care about someone scanning my barcode which I thought gave me my time and position, I was just happy I managed to finish what position I came in no longer mattered to me. So, I just laid down on the grass and decided I would take a few breaths before looking through my phone for the barcode I got in an email. My Mum however had different ideas, she started rushing for me to sit up and get the barcode ASAP and called over a volunteer to scan it for me once I got it up. It still took around 30 or more seconds for me to pull up the barcode and get it scanned, in my discombobulated shape. Which at the time I thought meant that likely the people I overtook in the ending seconds of the race actually got a better time and placement, but I really didn’t care all that much I was just happy I finished and that I gave 100%. After the volunteer scanned my barcode and token, she told me to hand back my token. However, before I handed back the token I promptly chose to lay down for a couple minutes, walking to the volunteer that was 10 metres away felt like an impossible task for a couple of minutes. The walk back to the car I got a cramp in my calves which hurt but it also made me feel accomplished.
With hindsight I now know that it didn’t matter how fast someone scanned my barcode, and the token that I was given at the finish was actually the thing that determined my position and time. I don’t know how that works but it works. So all my stress straight after the finish may not have been justified. At least I know now though.
Huge thanks to all the volunteers, organisers, supporters and competitors who made it such a good day and challenge. Biggest thanks to my mum absolute legend for driving me there and back and supporting me whenever she saw me. I really recommend doing one of these Parkruns in your local area, but unlike me with some training behind you as you will hear the aftermath was not ideal. For health, fitness, meeting new people, challenging yourself it’s a really great atmosphere. It’s a good place to make friends I feel like, I noticed so many people talking to each other, especially if you are an older person. You don’t have to run people of all ages and fitness levels go to these events. I can’t recommend it enough it was great fun.
Now for the result! Cause even though I didn’t care straight after I finished, I did care afterwards. I managed to get a time of 29 minutes 16 seconds. Out of 182 park runners I managed to place 89th, I was 4th in my age group, and I was the 69th male finisher. Which I found ironic as Magnus the person who inspired me in part to do this finished in 69th place. I wasn’t quite as good as Magnus with my placement overall, but I tried my best and most importantly I tried and found out whether I could run a 5k without stopping.
Aftermath and next steps
I am writing this 5 days after the race. The 3 days after the race were the worse. My lower body and lower back were done. I must have looked like a goblin walking up and down the stairs. Whenever I put too much pressure on my feet I would be in a lot of pain and cramp up. The day after the race I woke up from the pain in my legs. That bit wasn’t fun but I’m happy to say I am now fully recovered.
Since the race I have done more research into running and found that a sub-20-minute 5km is good. Therefore, I would like to run a sub-20-minute 5km. So that’s what I will aim to do hopefully running one before 2025 finishes. But like most goals I image this will seem a lot more undoable in the timeframe, once I start working more towards it. Still I’m going to try and go to Parkruns every 2 or 3 weeks alongside more cardio sessions in the gym going forwards to work towards that goal.
Oh and me running the 5k Parkrun has got my mum considering doing one as well, which makes me happy. I saw the fire in her eyes before, during and after the race. With her later letting me know she wants to try doing one too.
My next goal big is Hyrox stay tuned for updates once I complete that too later in September!
I might discuss my training for one in another blog before I do it. Let me know if you would like that, It would likely be a lot shorter than this one.
Comment and let me know about your experiences running a 5k! And give me ideas on other Physical challenges you would like me to try or that exist out there.
Have a good day!
All the best,
Kuba
