Glen Ogle 33: An Autumnal Ultra Marathon


Glen Ogle 33, often hailed as one of Scotland’s hidden treasures, unfolds as a 33-mile ultramarathon along the historic Rob Roy Way. Named after the infamous Scottish outlaw, it’s more than a race; it’s a celebration of history, nature, and the sheer joy of running. Crafted to showcase the breath-taking beauty of the Trossachs National Park, Glen Ogle 33 has become a perfect race for first time ultrarunners seeking both challenge and spectacular scenery.

The Glen Ogle 33 stood as a significant milestone in my ultramarathon journey, representing my sixth ultramarathon this year and the first race since I teamed up with a coach through Pyllon, my first experience being coached.

Ultra Marathon Nerves:

It has been a long time since I had followed a structured training plan. My first ultra marathon, the Ultra X 50km, I followed a plan through the Runna app. After that, I bumbled along through the Summer, creating my own training plan mixing in various ultra marathons. So very little actual structure! Now, after the Loch Ness 24, I had commenced a training plan created weekly through my coach. Although I had thoroughly enjoyed all my ultra marathon experiences, I was now ready to take things more seriously, and focus on getting stronger. But this came with added expectations I put on myself, and found myself starting to doubt my ability. Especially as it has been almost 3 months since my last ultra (lol!).

So, there I was, nerves doing a tap dance in my stomach, all the questions swirling in my head. How’s my body going handle this after the summer of ultras? My longest training run – a solid 20 miles, was all there was banked, was this going to be enough? Can I endure 33 miles? It is funny how you quickly forget your capabilities. Just the usual pre-race dramatics, you know?

The Morning of Glen Ogle 33:

Before immersing myself in the world of ultramarathon challenges, a ritual breakfast was in order. It’s not a fancy affair, just a simple staple—a hearty bowl of porridge jazzed up with chia seeds, generously topped with frozen berries, and a drizzle of honey. And, of course, a steaming cup of coffee on the side. It’s a familiar routine, the comforting prelude to the miles that lay ahead.

After a solid breakfast, I hit the road to Killin with a pre-dawn drive. Left just shy of 6 am, because who doesn’t love an early morning road trip before a 33 mile run?

The mission was clear as daylight: get there before 8am to tackle the registration chaos and secure that race bib. Stepping onto the event grounds, my initial morning jitters did a 180, turning into an electric excitement that could power a small town. The air was thick with the anticipation of what lay ahead, and let me tell you, it was contagious. Reuniting with the run crew added that extra layer of good vibes.

In those pre-race moments, surrounded by the run fam, the banter commenced, stories flowed like a pre-race feast, full of experiences, tips, and laughter.

Amidst all the chit-chat and soaking in the collective hype, I grabbed a banana. Because, you see, eating 30 minutes before the race is like the secret sauce, ensuring I’m loaded up with energy for those make-or-break first few miles. It’s the runner’s version of a power-up, and you bet I’m not skipping that ritual.

Nutrition Strategy Unveiled:

Fueling during an ultramarathon is a science I’ve honed through trial, error, and lots of sweat. Like clockwork, every 30 minutes, I consciously refuel—a habit finely tuned over months of experimentation. It’s not about eating when hunger hits; quite the opposite. It’s about feeding the machine, even when your stomach isn’t on board. The payoff? That sustained energy when your body screams for it later in the race.

My bullseye: 50g of carbs or 300 calories per hour. A figure I’ve meticulously fine-tuned through dedicated practice, and let me tell you, it works. This nutritional strategy isn’t a shot in the dark; it’s a deliberate choice backed by experience and a deep understanding of what my body needs.

Sure, it demands commitment, and yeah, sometimes eating feels more functional than pleasurable. But it’s a small sacrifice for the colossal benefits it brings in the later stages of a gruelling race. Sticking to this nutrition plan, even when you don’t feel hungry, is essential for ultrarunning performance.

When it comes to fuelling for ultramarathons, I go beyond the usual energy gels and bars. Real food is non-negotiable—a ritual that’s as much about energy as enjoying the journey. For the Glen Ogle 33, my pack was a carefully chosen arsenal to keep me in the game. In the mix were my 5 trusty bananas, a comforting jam sandwich, and a classic PB&J sandwich. Figs and sugar ginger brought a natural boost of carbs and bite-sized energy.

Hydration was as crucial as the fuel. Two 500ml bottles—one with water to douse that relentless thirst that comes with long distances, and the other with Hi-5 electrolytes to replenish what my body sweats out.

In this journey, I’m gradually pushing boundaries, increasing my carb intake per hour. It’s a calculated progression, a slow evolution based on what I’ve learned about my body’s needs. This nuanced adjustment mirrors the dynamic nature of ultrarunning, where success isn’t just in the miles covered but also in the thoughtful choices to sustain the body through the relentless demands of the trail.

Sharing Miles, Creating Memories:


As the race kicks off, I make a conscious decision to take it easy, like super slow. Why? Because I know it’s an investment for the later grind. This is my time to soak in the vibes and, boy, do I chat away. I hook up with my good friend Rachel, and together, we clock 18 miles. We’re not just about the miles; we’re about the banter too. Talking to other runners as we pass by, sharing stories, and making the most of those initial miles—it’s what makes the race more than just a run. It’s a social adventure on the trail.

The Unpredictable Predictable Pitstop:

Following the unspoken rule of ultrarunners – when it’s time, it’s time – I embraced the call of the wild, seeking cover wherever I could find it. A cheeky hop over a wall became my makeshift restroom, with just enough privacy from the fellow runners passing by.

Sure, it’s not your everyday pit stop, but it’s the kind of stuff you roll with in ultrarunning. The course becomes this canvas of both expected and out-of-the-blue challenges. After my brief detour, I hopped back over the wall and got back to the run. While there are usually portaloos at the checkpoints, those spots can be miles apart. So, you learn to be resourceful and add a bit of unpredictability and humour to the whole ultrarunning adventure.

Memorable Encounters Along the Way:

Alright, let me spill the beans on one of the absolute highlights from my stint at the Glen Ogle 33 – running alongside the legend, Alan. This guy was something else, let me tell you. We clocked a good chunk of miles together, and in that time, Alan’s ultrarunning tales blew my mind.

Now, Alan’s ultrarunning resume was like a checklist of every insane race out there, and then some! What got me was the frequency – practically every weekend, he’s out there tackling a new, daring ultra challenge. The man breathes passion for this sport, and every story he shared reflected a genuine love for the thrill of each unique ultramarathon.

As we pounded the trail together, little did I know that this race was a big deal for Alan – his 100th Ultra event! Finding out about this epic milestone turned our shared journey into a full-on celebration. The guy was a force – volunteering, supporting events – the whole shebang. His dedication inspired me to think about doing the same for future races. It hit me that ultrarunning isn’t just about personal victories; it’s about weaving this collective spirit, fuelled by shared experiences, support, and a deep love for the sport.

The Final Push:

About 6 miles left, Alan, being the absolute legend he is, nudges me to continue on without him, and so I picked up the pace. We’re surrounded by this unreal scenery, and I’m like, why not? Legs feeling surprisingly fresh and determined, I go for it.

As I navigate the viaduct, taking in the jaw-dropping views, a curveball hits—I’m struggling to munch down my last banana. Nausea creeps in, throwing a bit of a damper into what had been a run filled with endurance and resilience.

Looking back, it hits me—I probably messed up on the hydration front. Five hours in, and I’d only downed a measly litre of water, forgetting about the electrolytes too. Not one to let a banana get the best of me, I keep nibbling as I trot towards the final checkpoint.

Big decision at the checkpoint—hydration takes the crown. Instantly, it’s like a shot of vitality hits me. Revitalised, I tackle the remaining miles, soaking in the downhill stretch. The power in my legs becomes this adrenaline rush, driving me towards the finish line with a buzz that screams accomplishment.

The Unexpected Finish:

Approaching the finish line was like catching a second wind. I kicked it up a notch as I rolled into Killin, grinning ear to ear. Passing fellow runners who had already conquered the course, we exchanged well-wishes. Little did I know, the finish line wasn’t where I thought it was!

A surprising twist awaited—an unexpected final lap around a park. Laughter bubbled up despite the surprise. I rolled with it, embracing the challenge and pulling off a classic sprint finish as I hit the actual finish line. Grabbing that hard-earned medal, I joined friends who finished ahead, sharing in the sweet taste of accomplishment.

Feeling the temperature drop post-race, a lesson learned from past races, I quickly change into fresh clothes, and grab a hot cup of coffee. I returned to the finish line, not as a runner this time but as a cheerleader, rooting for others crossing the finish line. The air buzzed with stories, laughter, and the genuine joy that defines ultrarunning.

This event wasn’t just a race; it was a standout moment of the year, a testament to my growing strength and endurance. Hitting a personal best with what felt like less effort was a thrilling confidence boost, priming me for the challenges lining up in 2024.

Navigating the Glen Ogle 33: A Practical Guide for First-Time Ultrarunners

As you prepare to tackle the Glen Ogle 33, let’s break down the key elements of this ultramarathon journey, offering practical insights for those venturing into the realm of long-distance running.

Start in Killin: The race kicks off in the charming village of Killin. Arrive early to soak in the historic charm and serene beauty. Ensure you have your essentials: well-fitted road or trail shoes, moisture-wicking clothing, and a hydration pack.

Traversing the Rob Roy Way:

Navigating the start of the race can be a bit of a shock, especially when faced with a straight uphill climb. In the initial three miles, expect an average elevation gain of over 180 feet each. While this might catch you off guard, it can actually work in your favour if you stick to a smart strategy.

Consider adopting the “go easy, go steady” approach. In many races, a flat start can tempt you into maintaining a fast pace early on, leading to fatigue later in the race. However, the uphill challenge right from the beginning encourages a more conservative and sustainable pace. Remember, hills present a different kind of challenge, so a steady approach will serve you well throughout the race.

Approaching Lochearnhead: After conquering the initial ascent, the course winds down the hill past the Rob Roy pub and onto cycle path 7. A noteworthy point is the realisation of the cycle path’s significant incline about 15+ miles later. While the undulating route may tempt you to keep a steady pace, consider strategic walking breaks to conserve energy, especially as the course enters woods and forest trails after the second checkpoint at mile 11.

Crossing the Glen Ogle Viaduct: Prepare for a highlight—the Glen Ogle Viaduct. Take a moment to absorb the panoramic views. The way out to Strathyre, the bag-drop location, the viaduct takes a gradual descent over 3 miles, but be mindful; you will return back along here and it will be a gradual ascent!

To Strathyre and back: This section presents undulating terrain. Conserve energy on ascents and use descents to your advantage. Keep a steady rhythm, adjusting your pace based on the terrain. Regularly assess your hydration and fuel levels. There’s a steep climb out of Strathyre, a great opportunity to refuel, eat, drink, and walk up the hill.

Returning to Killin’s Finish Line: After traversing back along the viaduct, you will enjoy a 4 mile downhill all the way to Killin. Approaching the finish line back in Killin, manage your effort for a strong finish. Acknowledge the cheers from fellow runners and supporters. Be mindful that to get to the finish line, a lap around the park is required! Remember to rehydrate and replenish with post-race snacks and a hot drink. Get a fresh change of clothes to keep warm. Embrace the banter and share your experience with the running community.
