It's not normal but like everyone else I think it's significant that it was a big-city race (we don't see much at all of this sort of thing at the local half). Local quiet half marathons, people tend not to forget to train, then turn up ill (or hungover) - they either turn up sort-of in shape or not at all.
1. collapse and transfer stink to sofa 2. "too stiff to stretch" 3. "must have cold bath" - run and get in hot bath 4. effusively thank my OH should a cooked breakfast and a smoothie arrive on a tray
so probably I think!
I usually take gels mainly if I am checking I can still take them, before a race IYSWIM. Otherwise a few quid in the back pocket and browsing the shelves of newsagents - prawn cocktail? and ribena? that'll do nicely!
Beginners has begun again - so far so good - the ex beginners did a Q&A which I think was really good - hope they will all keep it up but there is even a little waiting list! Except I couldn't decipher one lady's email address and I tried 3 or 4 possibles!
It's all very individual: you sound like you might be one of the lucky souls in decent nick to start off with, who can just pile in and yet stay off the injury bench.
"Tired" is OK. "Problems sleeping", "Grumpy", "a niggle that has stayed in the same spot for a week", "feeling like concrete EVERY morning", that's the sort of thing you need to keep an eye out for.
Sensible ideas are :
* keep an exercise log which also includes how your mood is and how you ate and slept * do things like strength (especially core stability) training, cycling, yoga or swimming, on your non running days * join a local club or start going to parkrun to acquire a lot of new friends to talk running with (and see how they screw up or succeed!) * have a protein+ carb snack ready for immediately after the run (peanut butter sandwich? Milkshake?) * do proper warmups and cooldowns after intense (speed) sessions (if you join a club and do speed stuff with them, they should do this) * keep an eye on your diet - google Diet Quality Score
and above all, ** enjoying it ** is actually a surprisingly good guide: "if you're happy and you know it" you're probably not overdoing it
