Whether you are a cyclist aiming for a new personal best or an athlete training for professional scouting, 21 mph represents a bridge between "average" and "elite" performance. 21mph to kmh - Symbolab 21 miles Per Hour is approximately 34 kilometers Per Hour.
Alternating between bursts of maximum effort (22+ mph) and recovery periods to raise the overall threshold.
Sustaining 21 mph requires a high level of cardiovascular fitness. For most, this isn't a "leisurely stroll" but a focused effort that builds the engine required for racing or long-distance endurance.
Depending on wind resistance and terrain, maintaining this speed usually requires a power output between 200 and 250 watts for an average-sized rider.
In endurance sports, maintaining a consistent pace of 21 mph (roughly 33.8 km/h) often represents a significant physiological "threshold" for amateur and intermediate cyclists. At this speed, an athlete is typically operating near their , the point where the body produces lactic acid faster than it can be removed.
"Key work" at this pace improves the body's ability to utilize oxygen and burn fat efficiently before switching entirely to anaerobic systems. 21 MPH in the Context of Elite Athletics
Only trained sprinters and elite professional athletes (such as NFL players or top-tier soccer wingers) consistently hit or exceed 21 mph during "work" or gameplay.
Heavy lifting (like the 100kg bench press reps seen in elite NFL prospects) builds the raw power needed for explosive acceleration.
For both runners and cyclists, efficiency is key. This includes maintaining a 90-degree arm bend while running or optimizing "wrist hinge" and rotational power in sports like baseball to ensure no energy is wasted.
