Data can’t tell you everything. How interoception and RPE help endurance athletes read effort, pace by feel, and rely less on the watch.

Good training plans prescribe ranges, not exact watts or paces. Why ranges build better fitness and how to use them in bike and run sessions.

Races aren’t won by the highest fresh numbers but by who keeps the most of them after hours of fatigue. Why durability matters in triathlon.
Fit athletes still underperform when the plan breaks down. How triathletes separate strategy, planning, and execution so race day goes their way.

Borrowing Morgan Housel’s idea of quiet compounding: why slow, invisible progress produces outsized results in endurance training.

Find triathlon speed gains through bike position, transitions, open-water skills, equipment setup, fueling, and pacing without adding more training hours.
Explore our newest articles on training, racing, recovery, performance, and the broader experience of endurance sport.
Each article reflects our commitment to thoughtful coaching, practical education, and helping athletes make more informed decisions.
Many of the articles in this library are written by Elizabeth Waterstraat, founder and head coach of Multisport Mastery.
Elizabeth brings 20 years of coaching experience and 26 years as an endurance athlete to her writing.
Her work explores the intersection of training science, coaching judgment, athletic performance, and the everyday decisions that influence long-term development.
Her perspective is informed by coaching athletes across a wide range of abilities, preparing competitors for national and world championship events, and continuing to participate in endurance sport herself.
The objective of these articles is to encourage athletes to ask better questions, understand their training more deeply, and make decisions that support their goals.
Reading about endurance training can help you develop knowledge, but applying that knowledge to your own circumstances is where the work becomes more complex.
Two athletes may have the same race goal yet require very different training approaches.
Their backgrounds, recovery capacity, available time, strengths, limitations, and responses to training all influence the decisions that make sense for them.
At Multisport Mastery, we use those individual differences to guide training and support athlete development.
Our coaching includes individualized programming, ongoing communication, performance analysis, and education that helps athletes understand the purpose behind the work.
If you’re looking for guidance in applying these ideas to your own training, we’d welcome the opportunity to learn more about you.
