Oh - from my experience the Greenway was absoulutely fine to run on - apart from the wind and rain. I ran through every single puddle (To let off some of the red mist that I still had) and apart from being wet it was firm and not at all rutted. If that section was too dangerous to run the full then it should be too dangerous to run the half and every single cross country / fell race should be cancelled immmediately.
I'll say it again. We run and race at our own risk.... The organisers know that, they posted it enough times on their website - and don't get them started on the dangers of isotonic drinks....
I posted at length somewhere else on this race.... Still quietly fuming, but coming to terms.
If the race was cancelled on health and safety because of a hypothermia risk, then fine... I can just about accept that, but they should've let the marathon runners make their own choice at the twelve mile cut off and cut the time limit to something that made the last finishers be coming home around 3:45 - 4 hours.
I thought the conditions were grim but I prepared accordingly - wore three layers and had a change of gloves waiting for me at 12 1/2 miles - knowing that conditions between 12-20 or so miles would have been great with that massive tail wind blowing me along.... I'd have been done and dusted hopefully in about 2:50 or so which is about the time the last half marathon runners would be coming in.
If the race was cancelled because of puddles on the Greenway and fears about what was underfoot then I am afraid that is just crazy. It wasn't pleasant underfoot but it was no worse than your average cross country race - and apart from the puddles it wasn't that muddy.
There was over a week of warning that the weather was going to be bad, they announced on the website the night before that the race was on - but we ran it at our own risk. To have a change of heart 5 minutes before the start of the race was not correct, in my opinion.
To those who've posted that elite athletes never wear garmins in races because they are as bad as IPods in providing technical assistance care to answer why Haile G wasn't disqualified in Dubai for having his very own giant pacing device...
I'd give the Nike Free's some consideration (I have the Free Run). I love(d) the old Lunarglides (I'm still training in my third pair) but the Free's in comparison feel like they are just on a higher level in terms of comfort and the feel of speed.
I've raced all distances in them from 5km to marathon - they also encourage mid/fore foot striking more than the lunarglides do.
Not everyone loves them but they shouldn't be dismissed.
A few years ago at the end of April / beginning of May - ran the London Marathon (2:59) then 4 days later cycled from Land's End to John O'Groats in 10 days then the day after ran the Silverstone 10k in 37 minutes. So I'd say it's very much possible!
I began training in February as I'd been off running a couple of months with injury. I'd cross trained in the meantime. Once I was able to start running I focused more on training for the marathon than the cycling, aiming to get out once a week or so for a minimum 60 mile bike ride. I was relying on the cycling fitness compensating for lack of saddle time.
The marathon went better than expected, the LEJOG was hard work - especially in the first few days as I hadn't fully recovered from the marathon, but after a few days I found my cycling legs and found that all the running helped loads on the hills in Scotland.
To be honest, your two events are months apart, so you could concentrate on the cycling up till June then after a week or so rest prioritise on training for a marathon. Once you've shaken the fatigue out of your legs you'll hopefully feel fitter for all the cycling - and those two hour plus long runs will feel like nothing after 9 long days in the saddle!
You could keep up with some running whilst training with cycling - I think that all but the most dedicated cyclists can benefit from some running incorporated around the bike rides.
