You only have to look at the fastest times of all time to realise the importance of maintaining/strengthening that whole dorsiflexion phase/area.
Good example of this.
When/What did your tight calf issues stem from?. Dehydration is a big concern, but you talk about supping caffeine/creatine etc which is probably the fastest way to dehydrating & being in hot weather too.
Something I would recommend to everybody who suffers from cramping is Drinking Himalayan Salt Sole which houses 84 natural trace minerals in just one (super) food & its a real super food. There is no way athletes get all those from diet alone.
Himalayan crystal salt is a full-spectrum salt. Instead of just getting sodium and chloride, you’re getting a full spectrum of trace minerals as well. Table salt is just sodium chloride. You don’t get the trace minerals in table salt, and it is those trace minerals – those other 80+ elements that you need in order to be a healthy, vibrant human being.
From being flamed in the previous thread there is no way I’m gonna talk about exercise recommendation.
Don’t forget the tendons. A chain is no stronger than its weakest link.
