This is untrue. Think about this claim: "Lose 2%, and physical performance drops 10%". Elite marathon runners finish marathons at 2-4% body weight loss. You're now saying they could run 1h50 if they replaced ALL sweat losses? Nope. We are quite happy dehydrated while exercising
Thirst during exercise is a poor indicator of how much you actually need to drink. By the time you feel it, performance has likely already taken a hit.
Research is pretty clear on this: people left to drink on their own volition during exercise consume only about half the fluids they need. The body's thirst signal lags well behind actual fluid loss, especially in the cold, where you often don't feel thirsty at all despite sweating steadily.
The numbers compound fast. A 185-lb person loses 1% of body weight at just under two pounds of fluid. Lose 2%, and physical performance drops 10%. Skill-based performance – accuracy, reaction time, coordination – deteriorates even before that.
Generic advice like "drink 8 glasses a day" doesn't account for body size, sweat rate, heat, or effort. Hydration during exercise needs a concrete target.

What is more important for your health?
Being fit or being skinny?
The graphs show pooled data from a meta-analysis, stratifying subjects for normal, overweight or obese, and categorising them into “fit” or “unfit” based on their VO2 max, MET or similar values.
Being unfit is associated with a similar risk across all weight groups, with the “obese fit” group only at mildly higher risk than the “normal weight fit” group.
Being obese clearly increases the risk of dying of cardiovascular complications. However, this effect can be greatly reduced by working on your fitness, irrespective of bodyweight changes.
TLDR. While being normal weight and fit is by far the best combination, being normal weight and unfit actually puts you at greater risk than being obese and fit.

Hitting the trails is a great way to get away from distractions when you need to focus on form, HR or pace. Navigation and road crossing etc. use too much brain power!

Hope UK runners are enjoying the post-storm sun and mud!
Taking it easy and working on my form, love the woods early doors!

Good training questions to ask:
• What is the aim?
• What is the cost of that aim?
• Am I ready for that?
• Am I executing correctly?
• How does this affect what I am preparing for?
What would you add?
