The only thing I ever worry about is waking up one day and discovering i've lost the ability to actually run at all.
If your times bother you then leave the watch at home and run into the hills. You'll have no idea how far or fast you've been making it irrelevant. You can tell yourself it was 7m/m pace if it makes you feel better.
Worries about life are easily dealt with (or forgotten about) on a run.
Keys should never be an issue. Surely you have one item of running clobber that has a pocket or zip?
I live in the country so needing a poo isn't an issue. I have had to stop on a couple of occasions, retrieved emergency wet wipe from shorts, and done the business. I've been watched by approximately 40 sheep on one occasion and a herd of cows on another. The only time I ever really got a little worried was under a motorway bridge. I've no idea why as everyone was doing 70mph, how the hell were they going to see me, let alone recognise or identify me?
When I started running I recorded my runs in a diary, keeping nothing but the time spent on my feet. Looking back over it, it was great to see the gains in how long I was spending running. I have no idea what the pace was (probably for the best) but I was so proud to write 60 minutes non stop after a number of weeks building up. It's such a great motivator. Good luck with your training and +1 for strava.
No long run this weekend, just lots of chocolate. Nice run with Mrs JR today with my youngest on his bike, 3.45 easy miles around the country lanes. Had a very rested weekend but looking foward to training stepping up this week as it's 5 weeks until the Hartland Heartbreaker now.
Why haven't you been able to train? If it's because of injury are you okay to resume running for sure?
If it's not due to injury, in which case I would ask professional advice from a physio, you've plenty of time. You're way ahead of a beginner in the sense you've already done a marathon even if it was 8 years ago so you know what it takes to complete one. If you can run 14 miles now you're on track with any 16 week schedule I would think. The fact it's multi terrain and there's plenty of climb suggests time will not be an issue or target for you.
Personally I would run as long as training continues to go well from now and you're happy to accept you may take a little longer than if you'd completed a straight forward training plan without a gap for whatever reason.
