The night before your race isn't wasted time — it's the last training session you'll get, and it happens entirely in your head. Here's how to use sports psychology and physiology to walk into the Media Maratón de Bogotá calm, rested, and ready.
Why the Night Before Matters More Than You Think
I've been on the start line at altitude enough times to know this: the race doesn't start when the gun goes off. It starts the night before, when you're lying in a hotel bed in Bogotá at 2,640 meters, heart rate a little elevated, mind racing through start corral logistics, wondering if you drank enough water today.
Here's the coaching truth nobody tells you clearly enough — one bad night of sleep will not ruin your race. But how you manage the anxiety, the physiology, and the mental noise in those 12-16 hours before the gun absolutely will shape how you feel at kilometer 15, when the Circunvalar climbs start biting back.
Let's break this down the way I break down training blocks: mental, physical, spirit. Three systems, one athlete.
The Physical: Your Body Doesn't Know It's "The Night Before"
Physiologically, your body is still adapting from months of training stress. Recent work on exercise biomarkers [PMID:41922043] reinforces something I tell every athlete I coach: the taper period is not passive rest, it's active recovery where your biological systems — inflammatory markers, muscle repair pathways, autonomic balance — are still settling from your last hard efforts. That means the night before Bogotá is not the night to test anything new. Not shoes, not food, not a foam roller technique you saw on Instagram that morning.
Altitude changes the math. At Bogotá's elevation, your resting heart rate is naturally higher, and your sleep architecture shifts — lighter sleep, more wake episodes, which is completely normal and not a sign you're undertrained. Don't panic if you wake up at 3am. Athletes coming from sea level especially need to expect this and plan for it, not fight it.
On cardiac physiology: research on endurance athletes shows that prolonged endurance efforts create measurable cardiac strain and adaptation patterns across age groups [PMID:40667749]. As a Masters athlete myself competing in the 45-49 age group, I pay close attention to this — our hearts adapt differently than a 25-year-old's, and that means recovery protocols the night before matter even more as we age. If you're over 40, this isn't the night to skip your usual routine because
