25-Minute Intermediate Cycling Time Trial

A structured bike time trial with warm-up, a steady 20-minute effort, and a short cool-down.

Warm-Up

Gradually raise heart rate and prepare legs for sustained effort.

Easy Cycling
Easy Cycling4 min
How to

A low-effort cycling pace that warms up your legs and raises your heart rate.

  1. Sit tall on the bike with both feet secure on the pedals.
  2. Start pedaling smoothly at an easy, steady pace.
  3. Keep light pressure through the full pedal circle.
  4. Slow your cadence to finish, then stop the pedals.
Form cues
  • Keep your shoulders relaxed
  • Pedal in smooth circles
Common mistakes
  • Bouncing your hips on the seat
  • Gripping the handles too tightly
Moderate Cycling
Moderate Cycling3 min
How to

A steady cycling effort that trains your legs and builds aerobic endurance.

  1. Set the seat so your knee stays slightly bent at the bottom of each pedal stroke.
  2. Sit tall, hold the handles lightly, and place the balls of your feet on the pedals.
  3. Pedal at a steady, moderate pace you can maintain.
  4. Keep your breathing controlled and your effort smooth.
  5. Ease the pace down before you stop pedaling.
Form cues
  • Keep your chest lifted
  • Pedal in smooth circles
Common mistakes
  • Bouncing in the saddle
  • Gripping the handles too tightly
Hard Cycling
Hard Cycling2 min
How to

A bicycle-style core move that trains your abs and hip flexors with alternating legs.

  1. Lie on your back with hands lightly behind your head.
  2. Lift your shoulders and bring one knee toward your chest.
  3. Extend the other leg and rotate your opposite elbow toward the bent knee.
  4. Switch sides with control, cycling your legs each rep.
Form cues
  • Keep your lower back close to the floor.
  • Lead the twist with your ribs.
Common mistakes
  • Pulling on your neck with your hands.
  • Letting your lower back arch as your leg extends.

Main Set

Sustained time trial effort.

How to

A hard cycling effort for time that trains cardio endurance and leg power.

  1. Set your bike resistance so you can pedal smoothly.
  2. Start at a steady pace and build to a hard effort.
  3. Keep pedaling hard for the full time target.
  4. Ease your pace for a cooldown when time is up.
Form cues
  • Keep your chest lifted
  • Pedal in smooth circles
Common mistakes
  • Starting too fast and fading early
  • Bouncing in the saddle

Cool-Down

Bring heart rate down and flush the legs.

Pacing the Anaerobic Threshold Line

Pacing the Anaerobic Threshold Line

Hard Cycling and the Time Trial effort target your lactate threshold—the intensity where lactate production meets clearance. Moderate Cycling primes your aerobic engine before you push into that zone, so your cardiovascular system isn't playing catch-up when watts matter most.

20 Minutes: The TT Athlete's Crucible

20 Minutes: The TT Athlete's Crucible

A 20-minute maximal effort is the gold standard for estimating functional threshold power, demanding sustained recruitment of slow-twitch fibers while your fast-twitch units buffer accumulating lactate. Pacing discipline in the first 5 minutes is the single biggest predictor of a strong finish.

Threshold Blocks Build Race-Ready Power

Threshold Blocks Build Race-Ready Power

This session follows a classic threshold block structure—progressive intensity across warm-up, sustained overload in the main set, and active recovery to flush metabolite buildup. To personalize it, anchor your Hard Cycling effort to an RPE of 8/10 or 90–95% of your max heart rate and track how that ceiling shifts week over week.
