Gabe Joyes’s iRunFar advice supports flexible ultra finish plans, thoughtful sleep planning, and individualized rebuilding after Achilles problems.
On October 27, 2026, iRunFar published an Ask the Pro feature with ultrarunner Gabe Joyes. The coach and race director addressed finish-time estimates, sleep during a 200-mile race, and rebuilding training after Achilles tendinopathy. His advice favors preparing for several possible outcomes rather than organizing an entire race around one prediction.
For ambitious endurance athletes, the useful thread is adaptability. A finish-time estimate gives the day some structure. It should also leave room for what actually happens on the course.
Joyes recommends preparing a range of finish-time estimates with corresponding splits. His illustration is a 50-mile race with separate plans for 11-hour, 12-hour, and 13-hour finishes. Those times demonstrate the planning method; they are not suggested targets for other runners.
He recommends grounding estimates in current fitness relative to previous years. Results from races with comparable terrain, climate, and distance can also inform the estimate. Another reference is the performance of familiar competitors who have already completed the target event.
The important distinction is between an informed prediction and a promise. Joyes advises adapting during the race instead of treating the original estimate as certain. Preparing alternative splits makes that flexibility part of the plan rather than something improvised only after the preferred scenario slips away.
This preserves ambition without making every decision depend on the most optimistic outcome. The faster scenario remains available. So does a coherent plan for a slower day.
Joyes also describes planning relatively short naps during his Mammoth 200 Mile effort. He chose times when he expected to become sleepy. His account includes an additional nap beyond the initial plan and a six-minute trail-side sleep when he noticed that he was not thinking clearly.
He separately describes a one-minute break with his eyes closed and his headlamp switched off. He explicitly distinguishes that eye rest from sleep. That distinction matters when reading the account: a pause for eye fatigue and a nap were different responses to different experiences.
Joyes says his effort was also steadier than his approach in 100-mile races. He describes maintaining a comfortable and consistent intensity rather than surging or trying to follow other runners.
For the reader returning after Achilles tendinopathy, Joyes emphasizes assessment by a physical therapist and cautious increases in running volume. His advice also looks beyond the run itself. The response immediately afterward and the following day belongs in the picture.
The iRunFar feature is practitioner advice rather than a research study. It does not report the ages of Joyes or the readers. His observations at the 200-mile distance come from what he calls his “singular experience,” and he states that he is not a physical therapist.
Separate sleep research provides useful context. In its review of preparation for night running, CTS summarizes a 2018 study that tested 92 runners at checkpoints during a 168-kilometer mountain ultra. Sleepiness and cognitive performance worsened as the event progressed. The poorest readings occurred in the early morning.
CTS also describes a 2024 survey involving more than 1,000 finishers from two mountain ultras on Réunion Island. In that survey, 80% reported at least one symptom they attributed to sleep deprivation. This was a report from participants in specific events, not an estimate for every ultrarunner or proof that sleep loss caused a particular outcome.
CTS further notes that sleep-deprived training was not associated with faster finishing times in that survey. That finding provides no basis for treating deliberate sleep loss in training as a performance advantage.
Together, these sources support taking sleepiness and changes in clear thinking seriously during overnight racing. They do not establish a universally correct nap duration or validate Joyes’s chosen schedule. The column also supplies neither a standardized Achilles rehabilitation plan nor a quantified safe progression rate. Applying its advice to athletes aged 35 to 65 is an audience-focused interpretation rather than an age-specific research finding.
With those boundaries clear, the useful task is to translate the advice into better planning questions.
At Reendure, our focus is translating sports science for athletes over 35 with both current performance and long-term participation in view. This feature fits that purpose as a framework for organizing decisions. It does not need to become a demand to overhaul training or race preparation.
Joyes’s pacing advice translates into a straightforward planning sequence:
The point is not to fill a spreadsheet with every possible outcome. It is to avoid making one prediction carry the entire plan. A slower scenario can still represent a purposeful race rather than the absence of a strategy.
For a veteran athlete, this is a useful distinction between commitment and rigidity. Commitment can remain high even when the original timetable no longer fits the day. Changing scenarios need not mean abandoning the competitive purpose of the event.
Our discussion of using several signals to judge race effort offers a related planning perspective. The question is how to interpret the race that is unfolding rather than defend the prediction made beforehand.
Joyes’s emphasis on comparable terrain also connects with reading a course as an effort plan. A finish estimate deserves the context of the event it is supposed to describe. A familiar distance alone is not the whole comparison he recommends.
The useful question from Joyes’s sleep account is not which exact nap length to reproduce. It is how the race plan will account for expected sleepiness and changes in clear thinking.
His account contains both preparation and adjustment. He anticipated sleepy periods before the race. He also changed the plan when his experience during the event called for it.
That is the transferable planning principle: anticipated needs and actual experience both belong in the decision. The timetable is a starting point rather than something to defend regardless of how the race develops.
The CTS survey finding also gives athletes a reason to separate overnight-race preparation from deliberately practicing sleep deprivation. The evidence described there did not associate that training behavior with faster finishes. Preparing thoughtfully for a night race does not require treating lost sleep as an achievement.
For an athlete rebuilding after Achilles problems, the most useful next step in Joyes’s advice is a qualified assessment. Personal symptoms and return-to-running decisions belong with a physical therapist rather than a borrowed progression formula.
The mileage total is only part of that discussion. Joyes identifies flat versus steep running and faster versus slower running as variables that may matter for an individual. His suggested monitoring points include symptoms during the run, immediately afterward, and the following day.
He also cautions against running through tendon heat or pain. That places the athlete’s response alongside the planned workload instead of making the training schedule the only reference point.
For someone accustomed to measuring progress through completed sessions, the practical shift is in what gets discussed and recorded. The question becomes more specific than whether the mileage was completed. It includes what kind of running occurred and how the tendon responded across the observation points Joyes describes.
Our broader discussion of planning a training reduction provides a related perspective on keeping long-term goals in view when the immediate schedule changes.
Joyes’s feature offers a modest but valuable message: prepare seriously without mistaking the plan for certainty. His finish-time advice supports multiple scenarios and corresponding splits. His sleep account shows how preparation and adjustment worked together in his own race. His injury advice directs personal decisions toward qualified assessment and attention to symptoms.
For endurance athletes over 35, that is a practical way to hold ambition and longevity together. Keep the goal clear. Leave room to revise the route toward it. A useful race plan should help interpret the day rather than insist that the day match the prediction.
