My course of study doesn't finish until June and, if I'm doing things right, I should have at least a few interviews over the summer.

Thank you to everyone who has donated already!
Rather than dwelling on the fact that 100ft is approximately equivalent to a ten storey building, or 6 London buses stacked on top of one another, I will tonight be doing my breathing exercises and visualising the dive, step by tiny step.
There will be plenty of time to reflect on the last 5 months. I also have many people to thank, including the thousands of people who have visited this blog, and I will do so after the dive. I'm excited to see many of my freediving friends, who have given me so much support, in the morning. But right now I'm going to sleep, dreaming of the deep green and the challenge ahead...
The next graph is a DNF swim of about 50m, which I did with at the start of the session. I had contractions quite early and came up 4 strokes after the first contraction.
Graph 2 - 50m DNF
Unfortunately, I don’t know the exact time I started and ended the dive, so it’s a little bit difficult to draw conclusions. Bearing this in mind, I find the following points most interesting:
1. As you can see, my heart rate drops by 70bpm during the dive! It’s very cool to be able to see the effect of the dive reflex in pictorial form. If I remember correctly, I had a 3 minute breathe-up before the dive.
2. The graph shows that my heart rate is lower at the beginning of the breathe-up than it is at the end! This is at odds with what I would expect; I’d expect a gradual lowering of heart rate during the breathe-up and then a slight peak caused by stress immediately before immersion. It looks like I need to review what I’m doing for my breathe-up.
3. My heart-rate is elevated before the breathe-up even begins. I just measured my resting heart rate on the inside of my wrist sitting in the cafĂ© and its 69bpm. Even this seems a bit high – I’m going to blame it on my lack of aerobic fitness (or on the hottie sitting at the next table reading Hemingway). Assuming immersion occurs just before 03:20, my heart rate is nearing 90bpm at the start of the breathe-up and it rises to 115bpm immediately prior to immersion.
4. Assuming (again) that I end the dive at approximately 03:21:20, there is a subsequent leap in heart-rate within a very short space of time – surely this can’t be good for you?!
OK, I have to rush off to training at London Freediving now! Harry's down in London doing a placement at the London Diving Centre and will be training with us tonight :). If anyone has any comments on the graphs, I would love to hear them...
Enough of that. Now for the Motivating Factors:
If you'd like to follow my progress, this blog should keep you interested and amused in the run-up to the challenge, which will take place in October. I'll post diary entries, photographs, videos and much more!
I also hope that I can convince you to make a donation to this very worthy cause. No, not the comedy sight of me in a wetsuit - the MS Society! Please donate here: www.justgiving.com/Grace-Capel
For those of you who don't know what freediving is, here's a video that will give you some idea. Obviously it hasn't been filmed on a single dive, but the reason I like it is that it's beautiful and gives a real sense of the feeling of freedom you get.
