In this episode, coach Mark breaks down exactly what you should and shouldn’t be doing during the base months of November, December, and January if you want to crush your 2026 season without peaking way too early.Most athletes mess this period up, this is the time to build durability, consistency, strength, and aerobic capacity so you can absorb real training when the season heats up.

Most running injuries are preventable, and usually self-inflicted. In this episode, Coach Mark breaks down the real reasons runners get hurt and how to stay healthy for the long game.

He covers topics like: ramping up mileage too fast to running the same pace every day, skipping strength, or ignoring early warning signs, this episode covers the training, lifestyle, and recovery mistakes that quietly add up to injury.

Why your plan should always be written in pencil, and how simple habits like fueling properly, sleeping more, and varying your training can make you bulletproof over time.

FTP is a useful benchmark, but it’s not the only thing that makes you fast. In this episode, we break down why two athletes with the same FTP could finish 10–15 minutes apart and what actually drives real-world bike speed. From aerodynamics and bottle setup to durability, fueling, pacing, and momentum, we unpack the hidden performance factors that separate mid-pack riders from podium contenders.

Zone 2 training is incredible for building your aerobic base, improving fat oxidation, and making long efforts feel easier, but if it’s the only intensity you train in, you’ll eventually hit a performance plateau.

In this episode, I break down why Zone 2 alone won’t make you faster, how it fits into the bigger performance pyramid, and why you still need threshold and VO2 max work to raise your race pace, FTP, and repeatability in high-intensity efforts. I’ll explain why beginners often see huge early gains with Zone 2 while intermediate and advanced athletes quickly stall, and how triathletes, runners, and CrossFit athletes can layer higher intensities to deliver real race-day speed and durability. If you’ve been “living in Zone 2” and wondering why your performance isn’t improving, this will help you understand what’s missing and how to build a complete endurance engine.

Ever wonder what separates elite athletes from everyone else? In this episode, Coach Mark Cullen breaks down the key habits and systems that world-class performers live by: from training structure and recovery routines to mindset, nutrition, and environment design. Learn how to apply these proven strategies to your own training and life so you can perform like a pro, no matter your level.
