I just did the 5k of the last week of Ju-Ju's plan, only 4k & 10k to go.
However I am getting my old blister problem back. The last couple of runs including today I've worn a compeed blister plaster but today it became sore at 2.5k. It's where the shoe upper meets the sole at the base of my big toe (MTP joint). It's not blistered yet but very tender and it's developing a callus just under it (lovely!). The whole area feels 'delicate' so I don't want to file down the callus - it may be protective.
This started with my last shoes when I was building up distance and didn't happen when I changed my shoes 6 months ago. I wonder if I should consider new shoes again? But I have a 10k event in a month and don't want to have to cope with new shoes.
Any ideas? Sorry for the detailed description above π
