I've been biking since around October of last year, and then I can't remember specifically when, but sometime this year I hurt my knee due to a bad bike fit and so I had to take some time off and then sort of start over. My schedule basically looks like Monday through Thursday medium rides, Saturday big ride, rest on Friday and Sunday. So at this point I've been putting in around at least a 100 miles a week for a while now.

Just to clarify, since I increase by 10% each time my weekly big ride mileages are going to become 44, 48, 53, 58, 64, 71, 78, 86, 94, etc etc and it grows quite quickly (as do my medium rides since they're just half of what my big rides are). It just seemed odd to continue on in that fashion because of how large the miles are going to get and of how frequently I'd be riding them. So really what I'm asking is is there a point at which I stop increasing those weekly mileages, and if so what do I do (or maybe it's something like change what I'm doing during the week but keep increasing the big ride weekend mileages)?
