To put it in context, with the recent donations from Ian, Rob, Kate and Nick, I've passed the summit of a mountain you've actually heard of (Scafell Pike - the highest in England), but I've only just reached the summit ridge on Snowdon. And Aconcagua is nearly six and a half times higher than Snowdon is.
So, how do you train for a trek to nearly 7,000m?
When I was training for my earlier trek to Everest Base Camp, I joined a gym that had a hypoxic chamber. Inside it, oxygen was chemically removed from the air until it's equivalent to being at about 3000m. I found it fairly easy to cope with. My interval sessions [1] on the Concept II Rowing Ergometer, the instrument of torture of choice for boaties [2] everywhere, were just as horrible outside the chamber as in.
I eventually came to the conclusion that my daily commute was actually pretty good training for the trek. When I can, I cycle to work; 35 minutes in, 35 minutes out, a 15kg load in my panniers and - importantly - a filter mask that keeps out the London smog but also makes me work with a restricted airflow. As the time I was doing this 4 days a week and it stood me in great stead.
This time, I'm going to have to be more inventive. I'm spending 3-4 days a week in Edinburgh, which is not a feasible commute by bike. So I've been cycling into London when I can and thinking of alternative ways to simulate high altitude trekking in a country that is, as far as the Andes are concerned, flat.
Getting on the treadmill in the gym is an OK start; set the gradient as high as it will go, the pace as fast as you can walk and it'll do. But not every hotel has one, and it gets boring after a while. So I've been trying to be more inventive. Here's what I've tried so far:
- A family walk up Box Hill, carrying both my daughters
- A week cycling around Kent with daughter #1 (4, but bigger than some 6 year olds) on the front of the bike. Kent is always much hillier than I remember, but the reward according to the cycle computer was 100 miles ridden, and 9,000 calories burned
- Running up the South and North Castle Wynd in Edinburgh. These steps go from Grassmarket to Castle Terrace. I'm not sure quite how much of a climb that is, but go up them repeatedly on a morning jog and you know you've had a workout
- Walking from Putney to Twickenham for Quins home games (and last weekend to catch a coach to Leicester for the Tigers away game), carrying my son (7 and surprisingly heavy) up the gentle slopes of Richmond Park
- Signing up to help coach said son's mini-rugby team, which commits me to 2 hours of chasing the U8s around the pitch each week.
One thing I'm not doing is anything focused on upper body strength. As a big bloke, I need more oxygen than smaller folks anyway, which is an automatic disadvantage when there's less of it around. More muscle bulk equals more demand for oxygen, so I'm trying not to build up any muscles I don't need.
Any other interesting ideas for training, would be appreciated almost as much as more donations.
[1] The young lady who did my induction wrote "12 x 1 minute on, 30 seconds off x 3 sets" on my training plan. After a few weeks, I admitted that I'd only been able to fit in 2 sets in each of my gym sessions. She vanished with the chart and returned a few minutes later. "I'm very sorry," she said, "I should only have written 1 set." Ouch.
