This worked for me once. I rode 25k in 70 mins. But after that I slept for like 12 hours!
Hmm.. not working for me, fever is back, taking classes in such situation.
Take rest bhai.
I will once I'm back home. Another 13km ride.
To ride when you have fever is dangerous for your heart! Inform yourself by asking a specialist or reading articles in medicine
Get well soon brother! :)
