Ali: I promised myself - and everyone else, obviously - that if I completed our next training hike, I would be the one to write about it. I make it sound like a big deal, but it was.
The problem first came up during Training Hike 4. We were covering Stages 8, 9, 10 and 11, and I'd been traipsing along merrily enough until somewhere not far from the end of Stage 9 I was overcome by an incredible amount of pain in my calves. So I bowed out, disappointed, and left Martin and Chantelle to finish the hike.
A trip to the osteo and a bit of advice later, I set myself ready to do the Sarsen Trail with Chantelle, my husband Nick (first half marathon) and his dad (second half marathon). I got by all right on the first half, but at the 17-mile marker again I had to bow out for the same reason. This was getting rather silly.
Sitting in the car with Nick's dad on the way back from the event (he finished his half marathon no problem), we attempted to diagnose the problem and he said that something had definitely changed. A few rounds of pilates had sorted out the lower back pain I'd been having, true, but what else was there?
"You're not rolling as much anymore," he said.
And then: whammo. I walk all around London on tarmac and pavement all day long, no problem. What was so different about hiking about on chalk or sandstone? Shoes.
My trainers let my feet roll more, but my very sturdy-soled hiking boots didn't, because the soles were more rigid. An experiment was required.
Thus, Traning Hike 5.
I failed monumentally to be mature about this, and giggled most of the time we were sitting in the car park at Cocking Hill (*snigger*sorry) which was our starting point. This time we were covering Stages 3, 4 and 5, walking from Hilltop Farm to Littleton Farm, to Houghton and finishing off in Washington, giving us the goal of 30.1km.
Eventually at 11:15 we set off, having checked our backpacks, spread the OS map on the warmish bonnet of Martin's car, put on vast amounts of sunscreen, changed shoes andbade farewell - if temporarily - to Nick, who we left behind to eventually find himself some lunch.
The most significant thing about this walk was the fact that we were finally Four. After having done every permutation of Three, we were now a full team, making our way down the South Downs Way.
The weather was perfect, which was nice for a change on a Bank Holiday weekend: the sun was out, the wind was cool and the ground was dry and easy. Stage 3 is a lovely lightly-rolling ridgewalk lined thick with trees. Some bits of it gave us welcome shelter and it served well as a good warm up. And in my trainers I hardly felt anything, so it was all looking good. We eventually clocked the 8.3km in 1 hour 47 minutes, finding the car parked at the end of the lane near a small green.
Enough to set up an impromptu picnic!

Martin, with his back to the camera but sunglasses inexplicably on the back of his head, Mark, me, and Chantelle.
We took this time to have a look at the terrain map that Trailwalker had provided us, to see the long, long climb uphill, which was followed by another long, long climb uphill. I had some hesitations about doing that much climbing in my trainers, so I swapped back to hiking boots, to continue with the experiment.
The nice thing about scaring yourself with these terrain maps is that often when you get there, the climbs aren't as violent as they appear to be. I'm not saying they were easy, but they just weren't as forbidding. Either that, or we've come a long way since nearly smacking into Beacon Hill back in Stage 2 and thinking, "We have to walk that?"
Meet Bignor Hill.

Quite nice, isn't it? Chantelle and I had just caught up to the boys, who were busy learning about the local wildlife. There are also lots of pieces of Roman history dotted about, one of which is Chanctonbury Ring, which we'll go by on our next walk.
What was nice about walking as Four finally was that we essentially walked in pairs, which meant someone always walking with someone, and this made everything much easier and more enjoyable. I'm pretty sure we got to a point where it wasn't so much a training hike anymore as it was four geeks wandering about and talking all day. Which was great, and something we very rarely get to do anymore. I think we covered the usual things: gaming, movies, TV shows, comedians we'd been to see... and somewhere for whatever reason Chantelle and I educated Mark and Martin as to what Toreador from Carmen sounded like.
But hey, we're just doing what geeks do. Which is be generally, intellectually silly.
Stage 4 had a section that hairpin-turns on itself and led us up onto a path on the side of a hill, which gave us such a spectacular view that we could see white cliffs far off in the distance. And with all the fields of yellow the English countryside never looked so good. Unless you're hayfeverish.
Experiment-wise, let me just say this: about two or three kilometres to go, I was deeply, deeply missing my trainers. My calves were starting to seize already.
But we got to the checkpoint with no further issue:

Stage 4 was 9.3km long; we did it in 2 hours and 20 minutes. A very nice time indeed.
Another break later - and time for me to swap shoes again whilst fighting off a cramp in my stupid leg - we were off with the darkening sky above us.
Stage 5 opened with a long, long, swear-worthy climb. The boys waited for me and Chantelle at the top of the climb, holding the gate open like the gentlemen they were, after which I ravenously ate an apple and lost a cereal bar, which Chantelle - bless her - actually ran back down the hill to find. She didn't have to go far, but still.
The climb was steep enough that when the ground finally evened out we went at a good clip. There was more ridgewalking here, though not quite as sheltered as Stage 3. Martin, Chantelle and I concluded the Stage 9 was definitely the best ridgewalk as it was the most pleasant and had the best views, and I think Mark was a little sorry he'd missed that one, moreso since based on our event start time we'd be doing Stage 8 some time in the night!
I had to have more breaks in between this time, not having slept well the night before and cursing the decision to wear the hiking boots at all. Clearly trainers was the way to go, all the way. They fared well enough on ths climbs, after all. We also sorted out a better walking strategy, because the boys often got so far ahead that they would stop to wait, but by the time Chantelle and I had caught up, they were ready to walk again, which meant we didn't get a stop.
Luckily this was taken on board quite well - at least I hope so; I was rather grumpy when I said as much - and we started evening out the pace and stopping together. Stage 5 was probably our most realistic walk, as there were a number of 5-10 minute breaks and the pace was steady.
It wasn't long before we were talking about food, and we navigated our way to where the checkpoint would be on the actual day - a field by the road, which was currently empty and with the gates locked - and started hunting for Nick. We found him and he led us up a hill to the car park, where we took the day's last photo:

Now that you see the height difference, you may agree that I may be allowed the occasional utterance of, "This isn't £%*&ing fair."
We finished our last stage for that day, 12.5km, in 3 hours and 30 minutes. Overall we were very pleased with our times; they were all neatly under the estimated times given to us for those planning to achieve the full 100km in 30 hours, so we were doing well and getting better at it.
Well, at least I felt I was.
Nick took us all back to Cocking Hill (*snort*honestly, sorry) car park where Mark had to head back home, and the rest of us went off into the nearby market town of Midhurst in search of a good pub.
And man, did we find a pub. Regular pub prices, astounding food. Martin had been waxing lyrical about sausages and mash and red onion gravy, and lo! There was. I got a steak that was actually pink in the middle, and between us a lot of drinks were consumed. It's been a long, long time since I downed two pints of Coke the way I did that night.
As we walked back to our cars, shivering in the cold night wind, I had a horrifying thought.
"Dudes. We're gonna have to walk in this cold on the day. On the night sections."
Martin said, "Yup."
I guess it's time to shop for the long underwear.
