Sounds like lesson learned Ryan... that's one positive to take out of it.
HM for me too yesterday... complete disaster.
I knew it was supposed to be a bit hilly but it was 1200ft of ascent in total. Went off following the 1:30 pacer as I was convinced I had this in me... he went off pretty hard but I was feeling good till about 5 miles when I could feel my left calf starting to strain, which it promptly did... stopped and stretched, walked a while, then gingerly started running again but the uphills were agony. Finished in 1:39 totally deflated. Load of energy left in the bank but once again my calves couldn't hack it... my last HM in May (pan flat) derailed at about the same distance after the other calf strained.
I've had some really good training sessions in the last few months without problems which makes it even harder to take.
I'll need a week to get over this injury.... seriously debating whether the marathon is even worth the effort... cost/benefit says not... I wouldn't be happy running slower than 3:15 and it's going to take a big toll physically.
At least it's sunny this week... can get out on my bike.
I'm asking myself the same questions re. the belt.... I use one in training but need 4x250ml bottles in it... this alone is a kilo more in weight.
I might take a hybrid approach.... take a couple of 250ml bottles of drink and use them between aid stations where I'll just take the water... I'll need something to carry my gels in anyway and the belt has loops for these.
Well... I joined the 20 mile club this morning Wasn't too bad in the end... felt reasonably easy at 5:12/km (5:0x/km on the flat)... one thing I'm very pleased with is I think I got the nutrition right, didn't really feel like I was going to hit the wall at any point.... drink every 2k and gel every 8k seemed to do the trick.
Now... could I really run the whole thing in my planned 4:37/km for a 3:15 ? I'm not convinced, but I reckon 4:5x/km for a 3:30 is definitely doable.
