Geneva Marathon Training Log

8 weeks to go: 11-17 March

After a week with no training due to having flu and then an easy week to resume training, this was my first week in the final phase of training for the Geneva marathon. I was happy with the week overall and that I managed two quite solid sessions. I struggled a little with sore quads which was something that impacted me for a few weeks after being sick in December with a similar flu. I'm hoping to build on this week with more running distance and more focused marathon training sessions.

7 weeks to go: 18-24 March

That was a much better week and more like where I want to be! The total volume was good, I did three solid sessions, and overall I felt positive about the week. I had a slightly down day on Thursday (maybe underfueling?), but bounced back quickly for a good weekend of training. I'm getting a better sense of marathon pace and effort and I hope to dial this in some more over the coming weeks. I'd like to be consistent and keep this training going for another 4.5 weeks and then I should be in a good place to race well. I'm positive, but know I have work to do and that I need to be consistent.

6 weeks to go: 25-31 March

A solid week with some good sessions. Towards the end of the week I was feeling the accumulated fatigue and needed to take a rest day to freshen up a little. I'm starting to get a good feel for the marathon intensity and consistency, but I'm also learning just how hard it an event it is. I seem to respond quite well to training volume so the goal for April is to keep the volume high and dial in marathon pace.

5 weeks to go: 1-7 April

Another good week and just what I needed for my confidence in this build up. I felt stronger with each run and could feel the benefit of the increased training volume. I usually respond well to time on the legs and total training volume and that appears to be working again in this build. The high intensity sessions were hard and holding the pace and hitting the intensity when the volume is high is not easy, but I achieved what I wanted in the two key sessions this week. Another two weeks of building needed before it's time to taper and freshen up.
