Spooked

I wanted to go to the wood and the former golf course but I have been scared off due a young lady getting attacked very recently.
She was punched and kicked by 2 young lads who had electric bikes and it happened at the end of the public footpath i use to go to and from this route. The public footpath was the scene of a previous attack last year when 2 lads came from Liverpool to commit crime and they followed a young man before mugging him. 
The attack last year - CID took CCTV footage of ours which showed those lads followiung the young man.
As they were caught I didn't feel too bad about continuing to use that path then but now there has been another attack there I feel unnerved. The lads have not been caught.
The path is long and narrow with no access other than at each end. 
Therefore I went the longer route to the golf course which misses the wood. I still felt spooked on the quiet former golf course though as there was an attack on another one not far away recently when a runner (man) was mugged by some lads. 
I've often walked alone for the last 4 decades but now I feel spooked. I have an alarm but I can't run for more than a few yards and then I need to stop to rest!
I never carry money or bank cards when I am walking but I do take my phone and apparently they were after the young woman's phone. She has a black eye and other bruising but ran away (with her phone).
I couldn't face the long route return so had a quick peek at the PF in hope some walkers / dog walkers were going my way on it and luckily for me there were council workers at the "bad" end and no bikers around. Plus part way along I could see a dog walker so I went along the PF as fast as I am able to.
The extra photo is on the longer route to the golf course and this area by the rugby field near home was recently flooded.
Feeling apprehensive about walking.
