Runners are often asked why they run. Some additional exclamation marks can be added when the question is, ‘Why would you take on a 100-mile run?!!’ 

Well, it is a good question, in fairness! I will attempt to answer that here and share my experience of what it’s like to run your first 100 miler.  

So, how far really is 100 miles, further than the usual Ultra running distance?  I hear you ask. Let’s add some scale: 

·        3.8 marathons 

·        32+ park runs 

·        161.1km’s 

·        403 laps of an athletics track 

·        Equivalent of running from London to Brighton, then back again! 

In short, there is no short—it’s a long way! Now that you have an idea of the undertaking, let’s get into the experience of taking on the Rat Race Castle to Castle 100 as your first 100-miler. 

The stage was set. In the shadow of Bamburgh Castle, there was a countdown from 3, and then we took the first of 200,000 steps that would be required to cover the 100-mile run distance to Edinburgh Castle. The first-ever Rat Race Castle to Castle 100 miler was underway!

You’ve likely heard about the stages of grief. I think it’s easiest recounting the journey to the start line and along this 100-mile run in similar stages...!

Man running in sunshine

Denial – Am I really going to attempt a 100 miler? Am I mad?  

These were the dominant thoughts after hesitantly saying yes to a nonchalant email invite asking us to either run or crew this Test Pilot event. After giving the nod to run, every time the event came to my mind, it was with an accompanying thought telling myself, ‘It won’t actually happen; it’ll be postponed’ or ‘You won’t really need to do it’. Spoiler: it did actually happen! 

Lesson: Commit to it fully. Embrace the challenge, move past the denial phase early and get going with your training.  

Fear – Marathons are hard. How am I going to manage 4 of them back-to-back?  

When I talked myself into the possibility that this may be happening, the next stage was fear. Fear of pain. Fear of the distance. Fear of the unknown. ‘This is probably going to hurt… a lot’. I was anxious of the reality of it. I think this is normal, and if you aren’t anxious, please refer back to the scale of it and double-check you realise what you’ve signed up to! 

Lesson: Fear is a natural body response when we’re trying to protect ourselves. Channel that energy positively to help fuel your preparations. 

Excitement – Growth comes outside the comfort zone.  

After setting the denial aside, things get easier. If it’s going to happen, there’s no point being fearful. Time to be practical, and you may as well find reason to be excited. That is in abundant supply here. Firstly, it’s renowned for being a beautiful stretch of Northumberland Coast that I’ve never visited before. Experiencing new places on my own two feet is one of my biggest motivators for running. Secondly, the furthest I’ve run before is 100km, so this is a massive step up. With that comes a lot of excitement for growth and achievement. I tried to hold onto this feeling.  

Lesson: Remember, you’ve signed up for this in your own free time. Find the positives that excite you in your own journey and hold onto those.  

Worry – Keeping the demons at bay. 

Even past the initial denial and fear, worries still creep in. ‘Surely there’s no way I can actually do this?’ was a nagging voice that needed slaying. This was accompanied by the normal worries about my body giving up or DNF’ing through bad luck or lack of prep. Both were very possible, as prep had been lacking. I relied on my ultra running distance experience as I had done little specific training for the event. The more you train & prepare, the fewer these worries should be.  

Lesson: Start training and preparing now. The earlier you start, the more confident you will feel throughout your buildup and at the 100-mile start line.  

Acceptance – The easiest part, in many ways, is toeing the line.  

Signing up, training and managing your mindset can be mentally taxing in the build-up. Once we finally arrived in Bamburgh, it was a big relief. There’s still some usual last-minute nerves and excitement, but there’s no real point worrying about anything by then, as it’s just too late. The start line brings a welcome sense of relief that you can start putting one foot in front of the other and just get on with it. What will be will be! 

Lesson: Look forward to and cherish the start-line moment. Getting there is a huge achievement in itself. Try to relax on the day; all the work is done by that point.  

Tiredness – Well, what else would you expect?  

Picture this. You pull an all-nighter and cram a month of work into 24 hours. No, I’m not talking about my Uni exams. This is essentially what this event was in some ways. My training volume had been low going into this, and I only managed a few short runs a week, most weeks in the build-up, including a parkrun and one or two easy runs. It’s not an exaggeration, therefore, to say that this event was around 4 weeks of normal running volume crammed into 1 day. Get comfortable with tiredness. It’s likely to hit you like a wall when the sun goes down. The support around you will help you through this.  

Lesson: Expect tough moments. This is a 100-mile run, after all. Mentally prepare for times you may hurt or be low on energy and have coping mechanisms in place.
