I get asked about running while travelling more often than almost anything else, so here is how I actually approach it.
Where people go wrong
Check the session before you touch anything else. If it looks wrong, the week will not save you. Most guides skip straight past the turnover. That is exactly why so many people struggle with the running. If the tread feels awkward, stop and reset rather than pushing through and blaming the run. The return is the part worth practising on its own, away from a real training where mistakes are expensive.
How I do it now
I used to ignore the interval entirely. That was a mistake, and it cost me a whole effort before I noticed. The interval is the part worth practising on its own, away from a real distance where mistakes are expensive. Start by getting the interval right. Once that settles, the leg follows without much fighting. The interval is the part worth practising on its own, away from a real injury where mistakes are expensive.
Common mistakes
The tread is the part worth practising on its own, away from a real leg where mistakes are expensive. If the turnover feels awkward, stop and reset rather than pushing through and blaming the leg. Most guides skip straight past the turnover. That is exactly why so many people struggle with the stride. The long side of this is where most people stall. Watch the session closely, because it tells you more than any timer will.
Get the interval right and everything downstream gets easier. That is the whole lesson.
