I've been teaching for nearly 8 years now and started tri this year. Only done two sprints but now training for an Olympic and my first OW swim. I cycle to work one day a week 30 KM each way. I also try and go to a swim session at my local pool that is for the cost of any lane swim. I try to run a couple of times a week as well But this suffers as my bike and swim need the most work.
Fitting it in can get tough and it's a case of I do some of my best thinking when I'm on the bike or running. I've got into a routine so when I don't train I get grumpy and feel less productive at work.
Getting the balance is hard but your workload will never get less but you learn to work smarter. I'm a HOY and have a young family but you will find a way to fit it in I you really want it.
I have used red venom and find them good and much cheaper than 2xu or similar. They all seem very similar and if you can get aldi ones I'm sure they will be just as good.
I started using when I played rugby and kept getting calf injuries. Kept using them for running and they work well
The difference between the NB890 V1 and V2 was noticeable. Not uncomfortable but different as it had a lower volume toe box. I was able to try them and I get on with them really well.
I do however know of people who bought the V2 and hated it.
Try and find a pair. I know the sports direct near me had loads of NB shoes but no idea if they had any 860 in. They were all cheap though and I did buy some minimums trail shoes.
I'm another large runner. I've found that running on trails and off road has helped me to shake some of the niggles.
I tend to have an older pair of shoes for training and a newer pair for races same make and model. When training pair dies I buy a new pair to race in. I've found that I get more miles out of my NB 890 than any other shoes I've used.
