I'm sitting here rolling a tennis ball under my foot under the desk at work, waiting for my paper cup full of water to freeze to do an ice massage and trying to decide whether to run tonight or not! Plantar F probably caused by a combination of slight over-training and tight calves. Plan is to do a fast 10k tonight, 3 miles tomorrow, 15 fast-ish on Sunday (training for Berlin marathon). Or should I rest today and tomorrow, or should I get a massage today with the aim of stretching off my calves a bit - only 4 weeks to Berlin - oh what to do?!!! Help!!
