How to Keep Training When You Are Injured
Accepting the Situation
The hardest part of being injured during a training plan is accepting that the plan is no longer the plan. A beautiful 16-week marathon schedule existed. By week 9, the foot injury meant running maybe three times a week instead of five, and long runs were shorter than they should have been.
The engineering mindset helps here. There's a constraint. Work within it. Do not try to force the original plan, that makes the injury worse and costs more time in the long run.
What Changed
First, intensity was cut. Easy runs only, unless the foot felt good. Speed sessions were the first thing to go. Second, frequency dropped but the long run stayed. Getting one long run per week, even shorter than planned, maintained the endurance base. Third, cross-training on bad days, the bike does not aggravate the foot the way running does.
What It Taught
Fitness is more resilient than you think. Missing a week does not destroy months of training. Missing two weeks is not the end of the world. The body retains aerobic fitness for several weeks after stopping. What goes first is top-end speed, but for a marathon, aerobic endurance matters more.
The other lesson: running through pain is almost always a mistake. There's a difference between discomfort and pain. Discomfort you can work through. Pain is the body saying stop. Learning to tell the difference takes time.
The Adjusted Goal
The marathon goal moved from sub 3:30 to sub 3:45. Not a failure, a rational response to changed circumstances. A good engineer does not ship a broken product on time. Adjust scope, communicate the change, deliver something solid. Same approach to a marathon.

Five Weeks Without Running
My last run was the 27th of June. Since then it has been 26 gym sessions, five hikes, four kilos off and no running at all, with a half marathon booked for October.

Fifteen Wainwrights and No Running
Four days in the Lakes based in Coniston, three weeks after my last run. Harter Fell, Skiddaw, six fells above Ullswater and Grasmere, with an Achilles that still will not let me run.
