Night Criterium Race Preparation Diary: A Complete Guide from Gear to Mindset

Participating in a nighttime criterium isn’t as simple as “riding a bike at night.” From light setup to adjusting your circadian rhythm, from memorizing the course to emergency response, this article documents my complete preparation process for a nighttime race.

Getting the News: Three Months Out

A message appeared in the team’s group chat: in mid-December, a nighttime endurance criterium would be held on an industrial road in New Taipei City. Teams of four, relay format, riding from 8 PM to 2 AM—six hours total. Each rider completes one lap (about 8 km) per stint, then tags the next teammate in the exchange zone. The team with the most laps wins.

This was different from the individual nighttime races I’d done before—it was a team event, and a relay criterium at that. That meant everyone would be entering and exiting the darkness multiple times, pushing themselves to the limit again after short rests. It sounded thrilling.

I teamed up with three riding buddies: A-Jie is our climber, Xiao-Mei is the only woman on the team but faster than most of the guys, and Lao-Wang is the most experienced veteran. I consider myself the weakest link on the team, so I needed to be even more prepared.

Gear Checklist: Light, Warmth, Fuel

I divided the gear requirements for the nighttime criterium into three categories: light, warmth, and fuel.

For “light,” a criterium is different from a long-distance race—you don’t need ultra-long battery life, but you do need higher brightness, because criterium pace is usually faster. I chose a 2,000-lumen handlebar light with a beam pattern set to a spot-and-flood mix, so I could see both far and near when cornering at speed. For the helmet light, I used a 1,000-lumen model, sweeping the inside of corners with it before entering.

For “warmth,” December nights hover around 10°C. Your core temperature rises while riding, but cools quickly while waiting in the exchange zone. I prepared a two-tier system: a thin long-sleeve jersey with a windproof vest while riding, and a thick jacket with thermal tights to throw on while waiting. The key was quick changes—time spent in the exchange is time spent racing.

For “fuel,” the nutrition strategy for a relay criterium is completely different from a long-distance race. Each stint is only 15 to 20 minutes, so there’s no need to eat while riding. But over six total hours, you might go out six to eight times, so refueling during rest periods is critical. I prepared rice balls, bananas, energy bars, hot soup (in a thermos), and caffeinated sports drinks.

Course Recon: Once by Day, Twice by Night

Three weeks before the race, I scouted the course once during the day on a weekend. The 8 km loop includes a 2 km gradual climb, a 1.5 km technical cornering section, and a 3 km rolling section. The pavement was generally in good shape, but there were a few patches and manhole covers to watch out for.

After memorizing the course by day, I did two night rides over the following two weekends. The conditions at night were indeed very different from the day. Some sections that looked flat in daylight revealed hard-to-read bumps and dips under the beam of a headlight. I carefully noted every point that needed attention, even recording voice memos on my phone: “There’s a drainage grate at the exit of the third corner, pass on the left” and “There’s a false flat before the end of the climb, don’t get fooled.”

On the second night ride, I deliberately pushed the pace close to race intensity. The visual load at high speed at night increases significantly—your brain has to process all the information within the light beam in a much shorter time. This convinced me to switch the main light from eco mode to full brightness during the race, sacrificing some battery life for better visibility.

Adjusting the Circadian Rhythm

The race ran from 8 PM to 2 AM, spanning the normal sleep window. To help my body adapt, I started shifting my schedule two weeks before the race. Each night I went to bed an hour later, gradually moving from my usual 11 PM to 1 AM. At the same time, I scheduled a 30-minute nap in the afternoon to mimic race-day timing.

The race-day schedule went like this: normal work in the morning, a carb-heavy lunch at noon, a nap from 2 to 4 PM, a light dinner at 5 PM (rice with miso soup and grilled chicken breast), departure for the venue at 6 PM, warm-up at 7 PM, and race start at 8 PM.

Team Strategy

The four-person relay strategy would determine our final lap count. We discussed it at length and finally settled on this order: A-Jie (strongest) leads off to build an advantage while fresh; I go second, moderate but steady; Xiao-Mei goes third—she has the best recovery and can still hold high output after short rests; Lao-Wang anchors, using his experience to make the best strategic calls in the later stages.

Each rider’s target lap time was set at around 16 minutes. If feeling good, we could push down to 14 minutes, but not below 13 to avoid blowing up on later stints. Our principle: consistency matters more than bursts.

Race Report

At 8 PM, with the referee’s countdown, A-Jie shot off. The big screen in the exchange zone displayed live rankings and lap counts for each team. A-Jie’s first lap came in at 13:40, putting us in fifth place for the moment.

When my turn came, the darkness rushed at me. Leaving the lights of the exchange zone, all that remained was the narrow strip of road illuminated by my headlight. I was a bit conservative on the first lap—16:20. Back in the exchange zone, Lao-Wang handed me a cup of hot soup and said, “Take it easy, there’s a long way to go.”

As the night deepened, the race’s rhythm became more interesting. Every departure from the exchange zone felt like re-entering a parallel world—from the bright, noisy, warm exchange zone, suddenly switching to the dark, quiet, cold course. This repeated switching made my senses unusually sharp.

By midnight, fatigue was affecting everyone. On my fifth stint, the power in my legs had clearly dropped, and my lap time fell to 17 minutes. But what bothered me more was the drowsiness—while waiting in the exchange zone, my eyelids felt as heavy as lead. Lao-Wang noticed my state and handed me a can of caffeinated drink: “Two stints left. Hang in there.”

The Final Hour

From 1 AM to 2 AM was the last hour. At that point we were in fourth place, one lap behind third. A-Jie and Xiao-Mei both turned in laps close to 14 minutes on their final stints, and thanks to their efforts, we pulled level with third.

Lao-Wang took the final stint. He completed the last lap in a steady 15 minutes, and when he returned to the exchange zone, the clock had just hit 2 AM. In the end, we tied for third with 24 laps.

Post-Race Reflection

When I got home at 3 AM, my body was exhausted, but my mind was strangely wired. Lying in bed replaying the night, the images that surfaced were fragmented: the arcs of light sweeping through corners, the hot soup handed over by teammates in the exchange zone, the silence of the course at 1 AM with only a few headlights moving through the dark.

The most captivating thing about a nighttime criterium is its rhythm. Unlike a long-distance race, which is one long journey, it’s a series of short, intense efforts punctuated by waiting, recovery, and team interaction. That rhythm made six hours fly by, and it made the team’s cohesion stronger with every handoff.

We’ve already agreed to field the same team next year. This time, the goal: not a shared third place, but a solo podium spot.

To that end, I’ve already started training. Two night rides a week, each simulating race-intensity laps. Riding lap after lap in the dark feels like counting down to that December night.
