Training & Nutrition - Max Distance Threshold?

Is there a good way of gauging your max distance without risking being too far from home... to get anywhere or.... getting painful cramps all over your legs?

I Kind of want to see if I can ride more than 40 miles in a day. Around the 2 hour mark is where I always seem to start having some issues.

(these are all in San Diego, California)

I can bike 32 miles in about 2 hours and usually not get cramps.
My 40 mile ride to downtown La Jolla was great until I got to Torrey Pines hills, where my quads, hamstrings, and calves all started cramping up pretty badly to the point where I couldn't ride anymore. I ended up having to call for a ride home :P.

Just recently I rode 40 miles doing a circle of Mission Ave to Coast Highway to Palomar Airport Rd. and Back. I started getting pretty painful cramps doing the hills on palomar airport road from the 32nd to 40th mile.


Again all of these cramping points seem to start only after about 2 hours >.< On the bike.

I do always bring enough Water and Gatorade when I ride, but I have not yet tried eating
like every 15 minutes while I'm riding.

I'm currently waiting for my legs to recover (sore from sprints a few days ago)
so I can go to a long ride again (want to see my max threshold) >.<

Just wondering if there's anything I can do to really extend it or help with the muscle cramps.

I'm 130 lbs, 5'10'', 8% bodyfat.

Shift to a significantly easier gear and spin your legs instead of pushing hard. In short: raise your cadence. At your weight and age, I don't think there could be any other common cause. Water and some energy drink like Gatorade is plenty enough for two hours.

I tend to agree. What sort of cadence (pedal rpm) are you riding at? If it's low (say, under 70 RPM), that's your issue.

If you're up near 85-90 RPM, my guess would be something nutritional.

Spin, don't mash.

Aim to drink one 750 ml bottle of water and/or sports drink every 1 to 1.5 hours.

If you're out there more than 2 hours, aim to eat 250 calories per hour.

If you want to ride longer without being stuck way out in the middle of nowhere, ride loops.

And cyclists have ridden more than 800 kms (500 miles) in a 24-hour period of time ... something to gradually build toward. :D

XD thank you. My muscles will no longer be sore tomorrow so I'll bring food and drink along and raise my cadence/lower gears (its usually like 100 or so, but like... 60 or less on hills).
