adidas claims the Techfit Endurance Suit improves running economy by βmore than 1%β β around 48 seconds over a two-hour marathon. The interesting part: the manufacturer does not say this is about airflow. Polyurethane tapes stabilise the pelvis.
The largest analysis of marathon splits sorted runners into four pacing types. Among those who ran evenly, a collapse in pace in the second half occurred in 0.2% of cases. Among those who ran erratically β in 85.4%. The gap in finish time between the extreme groups is almost an hour.
Marathon runners ran for 90 minutes and then repeated their lab tests. Peak oxygen uptake fell from 56.7 to 53.4, and speed at lactate threshold from 12.8 to 12.1 km/h. This is durability β the quality your testing protocol never measures.
Flying across time zones costs roughly one day of adaptation per zone travelling east β and half that going west. We unpack where the asymmetry comes from and how to plan your arrival around it.
A good taper adds an average of 2β3% to your race result. We break down what the research says and lay out a ready-made 3-week plan for the marathon and half marathon.
Scientists gathered 340 runners from 24 countries, each with a hundred marathons behind them. Their aerobic power declines with age noticeably slower than the norm. We break down what it means and where the catch is.
The 2026 meta-analyses confirmed it: on the road a carbon plate really does save 2β3% of energy. But all the science on βsuper shoesβ is built on treadmills and steady pacing β and on trails and climbs there is simply no evidence of any benefit.
Two threshold sessions a day and a lactate meter in your pocket β we break down what in the βdouble thresholdβ is backed by science, what stayed pure hype, and how an amateur can try the method cautiously.
A fresh 2025 review explains why at marathons and ultras people end up in intensive care more often because of too much water, not dehydration β and how to avoid it.
Three world records in ultrarunning on a single day, historic NYC Marathon finish, doping scandal with world record holder, and ski season start in Russia. Top 20 news of the month.
