Blurred Vision After 30 Mile

[Stephenmacleod]

Anybody ever experienced blurred vision after a long cycle (30 mile). I got it towards the end of a 30 mile cycle a couple of days ago and wondered if it's common. Thanks

It sounds like your energy reserves might have been getting low. Did you eat anything before or during the ride? (Or drink some kind of energy drink to top you up.)

When I first started cycling I used to have the same problem after 30-40 miles. These days I am okay for that kind of distance but anything over about 50 miles I would make sure that I took a snack and/or energy drinks with me. (And a big breakfast before setting out.)

When I first started to cycle in hotter temperatures I could experience that around 90miles if I'd let my self dehydrate.

Heat, dehydration and no energy reserves. Quite common if you don't fuel especially when new to cycling.

Thanks for the reply. I only had a small bowl of cereal before heading off (early morning ride) and had a water bottle with me. I will definitely be sure to fuel up properly next time. Felt strong the whole ride and averaging a decent speed till the last few hundred meters then felt terrible. First time its happened and hopefully last.👍

Thanks for the reply, terrible feeling will be sure to plan better next time around.

Thanks for the reply, had a feeling it was something along these lines, terrible feeling. After a bite to eat, good drink and good couple off hours sleep it cleared up.

Chances are that you over-did it and are not as fit as you think you are. Pace is everything if you are not used to that distance and in this temperature. As long as you ate OK before, 30 miles should not require a fuel stop.

Heat exhaustion ?

Thanks for the reply mate, I only had a small amount before setting off in the morning with nothing else throughout the ride. Felt strong throughout the whole cycle and didn't feel it was to much it was just the blurry vision that got me. Definitely sounds as if I hadn't ate enough before setting off, one that I will definitely learn from. I've attached a screenshot of my pace/speed.
