Running

Treadmill can be great for elevation training - https://fitfortrips.com/calculate-elevation-gain-on-a-treadmill-hiking-workout/

Yeah that’s the part of Walthamstow I’m near. I think getting hills in should be ok. I also need to work on my scrambling. Plan is to head back to Norfolk a few times and get some longer runs in along the coast - I know people will say Norfolk is flat but the coastal paths are decently undulating and with the wind I think it will be decent enough training. The race is a loop of Windermere and having been up to the Lakes over NYe I’m excited/scared!

Oh nice and also thanks for the Orion routes - I had meant to save those at some other point and forgot!

Are you going to hit the ski trainer thing to minimise injury stuff?

Incline treadmill set at 12-15% with 10kg weight vest at 3-3.5mph for 1 hour+ session once per week is the key IMO. Did CCC in Chamonix with this as the foundation as also London based and rarely get into the hills. I believe stair steppers are better if you have access to one, but I've never tried one.

Wow that sounds horrible but have access to all of those things at my gym!

I’m planning to do a few Hyrox events this year so will be using the ski erg a bit as that training but not sure it will be hugely helpful for ultra

It really loads / stretches the calves which helps a lot I think.

Simulating downhill is less easy and more painful on the day! Single leg weighted step downs are a start. I did also do stepping up and over a 14" box turn round and repeat over and over but it makes you dizzy as hell so not sure it's worth it!

More in terms of cross training away from running.. is 100 miles a week training the norm for that sort of event,?
