Going All In on a Marathon Block as a Triathlete | Q&A
Wednesday, 23 September, 2026
Mikael Eriksson and Jack Hutchens answer listener questions, starting with a long look at how to fit a marathon into a triathlon year: when to do it, how much running it takes, what happens to the swim and the bike, and how far the long run really should be. Then questions on racing a 70.3 inside a base phase, coming back from overtraining syndrome, and whether you have to dig a hole to get supercompensation.We do listener Q&As monthly, the last Thursday every month.HIGHLIGHTS AND KEY TOPICS:Where a marathon fits in a triathlon year, autumn against spring, and the one situation where the less obvious option is the right call.Setting run mileage when you are also swimming and biking. Why the starting point is your own running history rather than a plan chosen by goal time, and what is wrong with how most marathon plans are built.A pro triathlete with a 60-minute record of 400 W at 78 kg asks why a 2:30 marathon still feels far away. What VO2max and fractional utilisation leave as the only possible explanation, and what can and cannot be changed about it.Long run distance against total volume, and the main point of disagreement between Mikael and Jack for this episode. Plus how far the longest long run should go, banded by goal time from a first marathon through to sub-2:30.Quads as the limiter in the marathon, from a listener with a 1:17 half and a 3:01 Ironman marathon. Conditioning, cadence, shoe drop and fuelling, and which of those actually matters.Racing a 70.3 in the middle of a base phase. The question to answer before you decide, and where Mikael and Jack come down differently on treating a race as a training day.Returning to training after overtraining syndrome. What to monitor on the way back, why HRV gets less weight here than you might expect, and the case study of a world-class skier who came back from underperformance to the top.Whether supercompensation requires digging a hole. Thirty-three trained triathletes, a three-week overload block into a four-week taper, and what separated the group that gained the most from the group that spent the study getting sick.SHOWNOTES, LINKS, RESOURCES AND RELATED EPISODES:That Triathlon Show Community on ROUVYThat Triatlon Show Group Ride on ROUVY - 5 October, 18:00 CET (12pm ET, 9am PT), 25 km / 15.5 miles on the Kona bike course.
