Sounds a good plan, give it a bit more time and quality less weight-bearing exercise. Focus on an intermediate challenge on the bike maybe and push the healthy eating to fuel you needs in the most nutritious way. Those uphill's are even tougher on a bike so a good way to work the climbing legs. Its always a bit of a fine line as when to ramp up again after injury and what kind of pain can be run through (more than you think is what I've learned over the years).
Enjoying my training post-Woldsman 50, more trail, hills, steps, etc.... and sun
Always nice to try things in a shop and I still get a lot of gear that way, but if like my area there isn't a huge off-road running focus there just isn't much in the way of running packs suitable for ultra to try on. All I can get locally is the old-style packs that are more like a 'lighter' version of a walking pack rather than the more running suitable wrap-around vest type.
If you look at the websites of some of the running pack manufacturers they will explain if any size options and what the size represents (e.g. a salomon s-lab pack of size M/L is aimed at the M or L top size wearer, S/XS likewise according to website).
I started out with an off-the-peg backpack which was fine, but I had to pull straps to very tightest setting and it still had some bounce in it. Went through a few lighter OMM packs which were pretty good at the price. Then I upgraded a few years ago and now run longer stuff in a Salomon Advanced Skin S-Lab 12 Set, 2013 model. Size XS/S which fits me well as I'm borderline XS/S t-shirt size. And its adjustable in various ways as I sometimes end up tightening loosening a bit depending on how much gear I'm wearing, if I've been overindulging a bit, and sometimes even tighten a bit mid-event.
I can only tell you what I know, but I can really recommend this model s-lab pack, very functional and sits nicely without much movement. Plenty of easy access front storage. Decent sized back storage and pretty expansive side access pockets. I can also recommend the original 5 litre version from 2012 which I bought first. The new packs look to have been tweaked and slimmed down a bit , no doubt based on feedback as they appear to be near half the weight of originals (and they weren't heavy) due to design and probably in no small part due to replacing internal bladder with soft flasks. They still claim the same capacities of 12 and 5L for the changes.
p.s. if these soft-flasks aren't your thing you can still get the 12L version with the good 1.5L bladder and front pockets large enough for bottles from 2013 now rebranded as 'Advanced Skin 12 set', but still available in 3 sizes. RRP isn't much cheaper, but here are doing a good price - http://www.ultramarathonrunningstore.com/Salomon-Advanced-Skin-12-Set-Backpack-p/saladvancedskin12set.htm (can recommend this retailer as they advised me on buying this pack from them in 2013). Only downside over newer packs is supposedly 530g vs 285g for newest incarnation with soft flasks. Can't say I ever found this pack heavy and what difference will a few hundred gram make to most once the pack is fully loaded with kit and water I figure.
I agree with GKD, plenty of time, fitness loss can be minimised by non-weight bearing activities possibly. And if not you'll be at quite a high baseline already so will not become a couch potato overnight. Maybe this is just me, but feels too early to get into heavy training atm anyway. I figure if I was doing 50 or more miles a week now I'd be burned out by well before end of August.
I just got myself to a mini-peak in training for a flatter off-road 50m which I did last week and now having an easy week or few before building back up and adding more hills in.
To throw a joker in there, I got one of these the other day. Seems expensive for its capacity, but in just one run I've got its use fairly sussed and it is very practical. I think it will come with me to a lot of future events. And you can cut the cost if you shop around (£4.50 at Rat Race before the member discount). Used it on aforementioned 50m which was an LDWA challenge event so they recommend you bring a cup and at this particular one you do need it as not all CP supplied cups. With my 5l pack there is limited up-front room and didn't want to be taking pack on and off at each CP to get cup out of back.
In practice I just had chest strap through the loop on back of this cup and its so light I didn't notice it there (and it was a windy day so if it was going to flap around annoyingly it would have). You could also squeeze it in to a pocket as when folded could almost go in your wallet. In event I had 750ml water in bladder for use throughout and in emergency (as didn't want to be removing and topping up). 550ml bottle of water + chia charge, which I just refilled at halfway. And then at various other CP I quickly stuck some of water or cordial that was on offer in this cup to wash down the biscuit, sandwich, etc.. I picked up and could move on fairly quickly.
Not easy to tell from picture, but basically put index finger and thumb through loops either side at top and you can hold open in a pincer. And then one side has a spout so you can drink without spillage. You can also walk, jog with it a bit easier without spilling than a standard cup because of flexible material. And the washing aspect doesn't concern me like for a bladder or soft flask as its easy to rinse or clean inside it.
Not really a solution to hydration in itself, but can work as part of a wider strategy
