Went to the Ponds Forge gym, which since the last time I went has moved from being in the main entrance hall into what used to be the Roundhouse. I was very impressed, a really good gym. 5 minutes warm up, then 60 minutes of 90/30s on the elliptical trainer, 5 minutes warm down.
Went to see brother Dave to get an expert diagnosis on my shin problem. It appears that the tendon is inflamed where it passes through some kind of casing on the top of the shin. This is giving me pain every time my foot flexes and the tendon moves, and is making a nasty creaking noise. Dave gave me some massage, and then strapped my foot to take pressure off the arch and the tendon. No running until at least the later part of the week, keep taking ibuprofen to reduce the inflammation, normal massage and ice massage, and cross-training as long as it's not aggravating the tendon. Fingers crossed now.
