Head Race

By the Watta Team · Updated

Head Race: A head race is a time-trial format rowing competition where crews start at intervals and race against the clock over a long course, typically 3-6 km.

What is Head Race?

Head races are processional time-trial competitions where crews start at intervals (usually 10-30 seconds apart) and race against the clock rather than side-by-side. The course is typically 3-6 km on a river or lake. Head races are the primary competitive format during autumn and winter in most rowing nations. Famous head races include the Head of the Charles (Boston), Head of the River Race (London), and Head of the Yarra (Melbourne). Head racing demands sustained aerobic power similar to a long erg piece — pacing is critical because the distance is too long to sprint. Erg fitness directly transfers to head race performance, and many rowers use erg times to predict head race results.

How Watta Uses Head Race

Watta helps head race preparation by tracking erg sessions at race-distance pace. Athletes can use Effort Score data from 5K-6K erg pieces to calibrate their head race pacing strategy.

Frequently Asked Questions

How does head racing differ from sprint racing?
Head races are 3-6 km time trials; sprint races are 2 km side-by-side (the Olympic format). Head races test aerobic endurance and pacing; sprints test peak power and race tactics. Most clubs compete in both formats across the year.
What erg distance best simulates a head race?
A 5K-6K erg piece at race pace best simulates head race effort. The intensity is around lactate threshold (UT1) and the duration is 18-25 minutes, matching most head race courses.
Do erg times predict head race performance?
Yes, strongly. There is a well-established correlation between 2K and 5K erg scores and head race results, adjusted for boat type and crew size. Faster erg times generally mean faster on-water times.
