Yes, I'm a marathon runner and long-distance cyclist and still active. Currently, I go to work by bike which is a commute of 26 km through the forest one way. I'm participating in a programme called "Go to work by bike" or "bike and business" funded by the ADFC - the General German Cycling Association and one German health insurance company. Employers can sign up for this programme and encourage their employees to take part. I've done over 500 km altogether this year.
My last half marathon was in February, and I got a better result than last year: 2 hours 10 minutes. During my last full (forest) marathon last August, I partly had to walk, however, not because of my hip but due to extremely hot & sunny weather and not having quite the training standard back (after I had to stop exercising and get my hip replaced in 2015). I have already registered for that marathon again and am planning to jog throught the entire 42 km.
It's been over 2 years since my hip replacement but I don't feel that I'm wearing it out. I believe in enjoying the 'here and now' rather than wondering what will happen when I'm 83. This is the age until which - as one surgeon told me - my hip should last, but I don't mind having a revision a few years sooner. Besides, I read about a Japanese study on the internet involving competitive runners with artificial hips that says there is no evidence that competitive running will cause their hips to wear out thus requiring a revision.
While I might still be alive in my 70s and 80s, I might be too lazy for jogging and cycling by then, but now I'm still active.
Of course my op was a single hip replacement (left). I can't give you any advice on bilateral hip replacements, but it should be exactly the same except on both sides (?).
Good luck with your job as a recruitment instructor.
