Indi, you are doing the right thing. There have been too many times when I pushed through the illness and I ended up with something really bad.
I am running I guess to do something different, as it seems the older I get, the more my body adapts to what I am doing. So, it really is for cross training, but there is a little part of me that is competitive enough, with myself, at least that wants to improve.
I am taking rest days. One day of complete rest and one that's an easy walk, spin, or just yoga or snow shoeing on easy trails right now.
The trip is to celebrate my 30th anniversary, which was actually in December. It's 10 days of the tour, with 8 days of cycling and 2 walking days. We are spending 3 days in Seville before the tour and 3 days lying on the beach in Malaga after. And believe me, i will be doing plenty of eating. No restrictions on food when I am doing this kind of trip.
