will it be possible if i can do 12.5miles on the exercise each night, to be able to do 54 miles in 2 months but i do have 2 weeks of exams about a month before it, or should i just go in for the 30 mile one? ofc i will be increasing 12.5miles over time
Exams are a bit of an ar*e when it comes to stamina - physical, drinking, etc. However one thing about exams is that you spend a lot of time sitting at a desk, thinking hard, but not doing much. When it comes to bed time you are mentally exhausted, but physically still bouncing. Your brain doesn't stop whirring, you can't get to sleep, and you lie in bed tossing and turning. The next morning you have problems getting up, feel tired all day, and the pattern repeats itself.
The best way out of this is getting some physical exercise that doesn't get in the way of revision/studies. Try a 30 min ride, e.g. just before going to bed, or just before supper. Or mid way through revision and before a quick late bite. Even a 10 minute ride is good, as it gives your brain just about the right amount of time to process the information that you have just read.
If you are young, fit and in good shape, 54 miles with 2 months training should be easy.
