Every time I go for a 2-3 hour ride I end up coming up feeling tired and I need to do some work after these rides. Any cures to this?
sleep
Er....
Do the work first?
Stop being a big girls blouse?
I could go on and abuse you a little while longer, but I think you might get the idea...
I admit doing the work first is better but in circumstances it aint possible. Is it just about getting more sleep and when I become fitter I will be less tired?
Power nap ? I used to sleep for an hour after hard road rides, did wonders.
Use the Graeme Obree technique and drink a pint of water before you go to sleep, that way you rehydrate and your bladder wakes you up.
Unless you are very old in which case you will wet the bed after 10 mins, so not such a good idea.
Sorry for sounding like a tool, but your question is essentially 'I do something that makes me tired, how can I stop feeling tired?'
You should get used to it over time, but if you are using the 2-3 hours on the bike in any kind of training sense, you will feel tired.
