As a biohacker and endurance cyclist with 15 years of rides under my belt, I was in my element: hammering up a mountain in 40°C heat, legs burning, heart pounding, and loving every second of it with my cycling club RCCLA in Ojai, California.
The ride was smooth sailing until a rookie hydration slip-up on the final climb taught me a lesson I won’t forget.
The Ride That Woke Me Up
I’ve been riding with RCCA for nearly a decade, surrounded by cyclists who live for the grind and inspire me to push past limits. Cycling is my sanctuary; a place to connect, suffer, and grow. This Ojai ride was set to be another feather in my cap: long distance, brutal climbs, and scorching heat. I was ready. Or so I thought.
I’m no stranger to extreme conditions. Years of cold plunging, saunas, and steam room sessions have made me bulletproof against the weather. It’s out of our control, so why stress?
Heat? Doesn’t faze me.
Cold? Love it!!
People complaining about bad weather? Pet peeve.
As we say in cycling, “there is no such thing as bad weather, only improper gear.”
The ride was a dream. I felt strong, the scenery was unreal, and I was thriving in that sweet spot where the challenge feels electric. Flow state.
But I made a rookie mistake: I didn’t nail my hydration.
At 55 km, I ran out of water. I hadn’t refilled at the first stop, feeling unstoppable (oops) and “pee anxiety” (ladies, IYKYK). My bottles were also low on electrolytes, and I had forgotten my salt tablets.
With 15 km to go until the next rest stop at 70 km, I glanced at my Garmin and saw the countdown to the minute. Those final minutes felt like an eternity. I usually skip loading routes on my bike computer to avoid psyching myself out, trusting my grit to carry me. It would’ve been agonizing to a younger Katy, but thankfully, I had built some insane grit over the last few years.
My mouth was dry and parched, but I leaned into a biohacker’s secret weapon: visualization.
I pictured myself chugging ice-cold water laced with my favourite berry-flavoured electrolyte packets, tasting every crisp, tangy morsel.
Our thoughts create our reality, and the brain can’t tell what’s real from what’s imagined.
The visualization was so vivid, every sip bursting with flavour, that my brain bought it.
My mouth started to salivate, easing the dryness and fueling me to keep pedalling.
All the while, I coached myself: “Everything is fine. You’re good, babe.”
Even though I was in a great headspace and the ride felt more like flow than suffering, that self-talk kept my focus razor-sharp.
When I finally rolled into the rest stop at 70 km, I was pumped but sloppy.
I grabbed bananas and chugged Coke, caught up in the vibe, but didn’t load my bottles with enough electrolytes. Big mistake for a biohacker… but I was riding high and let it slide.
That oversight didn’t hit until the final climb: 8 km with pitches over 10%.
That’s when things got real.
The Ojai sun blazed at 40°C, the air thick with heat. Fatigue crept in, my legs heavy for the first time. But I barely noticed the steep grades or scorching heat; I was locked on calming my body to keep cramps from spiralling.
Cramps started at the base—tightness in my quads, twitches in my hamstrings. Soon, my calves, hips, and lower back joined the revolt. It wasn’t a meltdown, but it was a wake-up call.
I told myself, “Keep pedalling, you’re good.” I used box breathing to stay calm.
Halfway up, I remembered a single salt tablet buried in my back pocket. Fumbling for it while grinding up a 12% pitch, sweat stinging my eyes, was no small feat. My fingers shook, my legs burned, but stopping wasn’t an option— if I unclipped, the cramps would’ve frozen me in place, and I’d be that girl sprawled on the side of the road.
I popped the tablet, praying its 1000mg of sodium would kick in fast. It helped, but it wasn’t enough to fully tame the beast.
The climb felt endless, but my focus on calming my body, through breathing, self-talk, and sheer stubbornness, kept the cramps from escalating into a full-blown crisis. I didn’t have time to dwell on the heat or the grade; my mission was survival mode, one pedal stroke at a time.
Finally, at the top, I was literally screaming in pain, and Gary thought he had to inject me with adrenaline, but he kindly hooked me up with his last two salt tablets. Legend.
I descended back down to the rest stop, chugged Gatorade, grabbed some bananas, refilled my bottles, and rode the final 50km home feeling great. The ride was a success, no question. That final climb was the only rough patch, and while it didn’t derail me, I know I could’ve nailed it with better hydration prep.
Lesson learned, and now I’m passing it on.
Why Hydration Powers Longevity
Hydration is more than chugging water— it’s about fueling your cells, boosting your brain, and setting yourself up for a long, vibrant life.
As a biohacker, I know that proper hydration optimizes mitochondrial function, aids in detoxification, and helps regulate stress hormones. Even mild dehydration can zap your endurance, fog your focus, and slow recovery.
For athletes, low electrolyte levels (specifically sodium, potassium, and magnesium) can trigger cramps or fatigue.
For longevity enthusiasts, chronic under-hydration stresses organs and accelerates aging.
My rookie oversight taught me the importance of electrolytes. Sodium regulates fluid balance, potassium supports muscle function, and magnesium drives energy production. Skimp on them, and your body will let you know, like mine did on that climb.
5 Pro Tips to Master Hydration
1. Pre-Hydrate with Electrolytes
Start hydrated. Drink 16–20 oz of water with 500–1000 mg of sodium (via salt tablets or electrolyte powder) 1–2 hours before activity. I’m all about berry-flavored electrolyte packets—they’re tasty and effective. Pre-hydration primes your body for action.
Biohack: Add a dash of Himalayan salt to your morning water for trace minerals. It’s an easy win.
2. Pack Electrolyte-Rich Water
For rides or workouts over an hour, use bottles with 500–1000 mg of sodium and 100–200 mg of potassium per liter. I carry two 750 ml bottles with a solid electrolyte mix. Plain water can dilute sodium levels, so don’t rely on it alone.
🧬 Biohack: Experiment with LMNT, Nuun, or Liquid I.V. Find a flavour that keeps you sipping.
3. Sip Consistently
Take 4–8 oz every 15–20 minutes during activity, even if you’re not thirsty. Thirst is a late warning sign. I got lazy about this in Ojai, and it bit me. A timer or hydration app can keep you on track.
🧬 Biohack: Ladies, plan pee stops to avoid anxiety. Hit a rest stop or find a tree and keep rolling.
4. Rehydrate Post-Workout
After exercise, drink 16–24 oz of water per pound of body weight lost, plus 1000–1500 mg of sodium and 200–400 mg of potassium. I pair an electrolyte drink with a banana or avocado for extra potassium and magnesium. It cuts soreness and boosts recovery.
🧬 Biohack: Mix in 3–5 g of creatine post-workout for brain and muscle benefits (a longevity game-changer).
5. Listen to Your Body
Your brain might say “I’m fine,” but your body knows better. Watch for early dehydration signs: dry mouth, fatigue, or mild cramps. If cramps start, pop a salt tablet (500–1000 mg sodium) and sip electrolyte water. Biohackers thrive by staying tuned in.
🧬 Biohack: Track your sweat rate (weigh yourself before and after exercise) to customize your hydration.
Mental Hacks for Tough Moments
When things get dicey, mindset is your secret weapon. Here’s how I powered through that climb:
- Visualization: Picture your goal—cold water, big win. It tricks your brain into staying focused.
- Self-Coaching: Say, “I’ve got this.” Shut down negative thoughts.
- Breathwork: Box breathing (4s inhale, 4s hold, 4s exhale, 4s hold) calms your system.
- Self-Belief: Know you’ll finish. Confidence carries you.
The Longevity Win
Hydration is a cornerstone of performance and longevity. It’s not just about nailing a ride but building a body that thrives for decades. My Ojai ride was a blast, with one small hiccup that showed me where I can level up. Prep your body with water and electrolytes, stay sharp with a strong mindset, and you’ll crush any challenge.
Ride strong, biohack smart, live long.
