I just did Brighton Marathon off 3 runs a week plus cross training. Target time set at the start of my 16 week plan (based on a previous marathon from a few years ago of 4.19, plus some more recent times/paces from some runs I'd done) was what I thought was a slightly ambitious 4 hours. I came in at 3.58.10. Could have I have done quicker with more running sessions each week? I don't know. But I do think based on my training and running ability that I did what was about the best I could do on the day, so in a sense 3 runs a week definitely worked for me.
I used the Run Less Run Faster (FIRST) as a basis, but tweaked it slightly in how I built up the long runs, and also did more (and at times more intense) cross training than in that plan.
I really liked the fact that every run had a purpose and there was no 'just general running' sessions. I also worked well with having target paces that are specified in the plan as I like structure and a clear aim! I found some of the paces for the interval runs challenging but they were achievable with some effort, and at times I found that I could manage faster. The way the plan is structured also meant I found it good in terms of tracking progress.
I came into the plan with quite a good fitness base as I am a rower, and I used rowing (both on the machine and on the water) as my cross training sessions. I found the variety of doing more than just running meant it never felt too much of a chore to get the 3 running sessions done each week.
There's also an app as well as the book for the Run Less Run Faster, which will give you all the paces for the runs if you input your target time - I think it might have cost a quid or two to download but saved looking it all up in the tables in the book, and was just useful for me to have it all on the phone. The book has a load more supplementary info though which some people would want to read.
And finally I believe that one of the key things for me was that when I was looking at plans and working out what to use I ended up with something I believed in - from the outset I liked it, I thought it would be manageable, and I thought that the way it was structured suited as the kind of training that I know works well for me and which I get results from. I'm not massively into saying stuff like this but whatever plan you go with has to be something you're prepared to sign up to and believe in. If you don't think you like it then it's probably the wrong plan!
You can only see the first 6 pages on there, but the others seem to be available in the background to claim your time. Sadly I'm not fast enough to make the top 6 pages but I did go to the Add Performances section and it seemed to validate my time ok
26.35 at Brighton this year, with a Garmin Forerunner 210.
Interestingly up until about 6 miles I was clocking almost dead on with each mile marker, then (and I can't quite remember which mile it was, maybe 7 or 8) I was all of a sudden 0.12 out. Seemed to get a bit back around mile 10, then lose it again around 11/12, and then gradually a tiny bit more throughout the 2nd half.
I knew I was going to be touch and go whether I could sneak in at under 4 hours, so when I was working out target paces I went on Garmin Connect a while before the marathon and looked at lots of other peoples from the year before - most were reading about 26.4x miles, so when I was working out paces I based everything on the pace to do 26.4 in 4 hours rather than 26.2. It's only a few seconds per mile but didn't want to get it wrong! In the end I had a good day and came in at 3.58.10 for 26.35 miles so had a bit to spare even if I'd done slightly further than that.
It's a roll of double sided sticky foam type stuff (fairly thin).
Cut a square for each corner of the number and hey presto. It sticks fine to both the number and to technical fabrics, and it's never come unstuck for me in the rain or wind. Indeed it withstood 4hrs and 19 minutes of torrential rain and gain force winds in the Greater Manchester Marathon earlier this year
I've got shingles at the moment too - I can sympathise! Leading up to the rash I was feeling pretty rubbish for a week or so and not really feeling like running anyway, and still don't to a certain extent.
Mine is still too painful to really be running, but part of that is because the rash goes over my shoulder and front of chest which is right where my bra stap would be - but judging by your name you won't have that specific issue!
I can't quite work out if my rash is actually painful, or whether it's so itchy and prickly that it feels painful too.
Being that it's caused by a virus I'd probably say that running isn't a great idea whilst your body is trying to fight it off, and when you do feel better the advice seems to be to return to everything gradually and slowly - sometimes easier said than done, but I think it's easy to think that once the rash has cleared up then that's it, which may not necessarily be the case.
