I recently trained for and ran my third half marathon - and I am now thinking that it is time for me to limit my "races" to 10K and to simply "enjoy" them rather than trying to set any kind of pace. I am now the fittest I have ever been in my life ( at age 70 ???) and my most important goal is to stay this way and continue with my running. I have lately concentrated on simply enjoying parkrun on Saturday - basically messing around and often running alongside slower runners - and doing much the same thing at my Sunday running club ( but with runs around an hour long as opposed to the 5Ks at parkrun) . Two other days of the week I quite enjoy doing harder 200, 400 metre and klm repeats at different paces by myself. And I am thinking of joining a local gym to do some weights strength training after we come back from our 6 week tour of the UK. I find the 10K distance to be sufficient "challenge" and I would like to be able to regard the 10K distance as "easy" (as I now do the 5K distance - my 100th parkrun this weekend) . I don't run 10K that often so I would need to concentrate on it a bit more to really "conquer" it.
I am looking forward to doing a bit of running while in the UK (actually hoping to run every day - but only short 20-30 mins at a time) - we have visited many times before - before i started running - and I am attracted by those canal paths . I have 5 parkruns in mind - but they will be very dependent on weather - being an Aussie , I don't do "running in the rain" (can't see though my specs!!)
