Background : Amateur/hobby runner, done 4 10k runs with personal best: 56 min.
I'm practising for my first half-marathon (due in 6 months), and am mainly looking to finish without stopping; no time goals for this one. I fractured my fibula 4 years back- it has healed, I still have the plate inside. Despite full recovery I am cautious and preventing injury is a prime concern.
The route is mostly road, with some flyovers in a coastal city, typical temperatures are ~ 30C. I ran a 10k on the same route and got pretty exhausted on the flyover. I'd like to practice for the slope, but there are no hills/flyovers near me. Can I run up and down stairs instead, will that help in a 21k run?
The possibilities of joint damage have been discussed here and the fact that it may simulate humidity is discussed here, but neither of these are targetted at distance-running, so I believe this question is not a duplicate.
